Low Carb Tuscan Chicken with Creamy Spaghetti Squash | Recipes by HomeChef

Okay, so picture this: I was knee-deep in a low-carb kick, feeling a bit bored with my usual chicken and veggie routine. I mean, how many ways can you make grilled chicken exciting, right? Then I stumbled upon the idea of Tuscan flavors. Rich, creamy, sun-dried tomatoes… but could I make it low carb? Oh, honey, yes! After a few kitchen experiments (and one minor sauce explosion, oops!), I perfected this Low Carb Tuscan chicken recipe. It’s been a weeknight savior ever since, bringing restaurant vibes right into my kitchen. You're going to love it!

Oh, I have to tell you about the time I first tried to make this sauce. I got a little too enthusiastic with the chicken broth and ended up with a runny, sad excuse for a Tuscan sauce. My husband, bless his heart, tried to be polite, but it was basically chicken soup. I didn't expect that! Lesson learned: follow the liquid measurements, or your Low Carb Tuscan chicken becomes a broth party.

Ingredients for Your Low Carb Tuscan Chicken Masterpiece

  • 1 1/2 lbs boneless, skinless chicken breasts: These are your stars, hon! I always opt for boneless, skinless breasts because they cook quickly and absorb all those amazing Tuscan flavors. I like to slice them into thinner medallions, it just helps them get that gorgeous golden sear and ensures they stay super juicy. Nobody wants dry chicken, am I right? It’s the foundation of our amazing Low Carb Tuscan chicken.
  • 1/2 tsp dried oregano, 1/4 tsp garlic powder, Salt and freshly ground black pepper to taste: My secret weapon for elevating simple chicken! These aren't just spices, they're the flavor backbone. Oregano brings that classic Italian warmth, and garlic powder just amps everything up. Don't be shy with the salt and pepper, they bring out the best in the chicken before it even hits the pan. Trust me, it makes all the difference.
  • 2 tbsp olive oil (for searing): Ah, olive oil! The golden elixir of the kitchen. For searing the chicken, you need a good amount to get that beautiful, crispy exterior that locks in all the juices. It's all about creating that perfect crust before it gets bathed in the creamy sauce. A good quality extra virgin olive oil really shines through here, too.
  • 1 small yellow onion, finely diced & 4 cloves garlic, minced: These two are the aromatic dream team, honestly. Finely dicing the onion means it melts into the sauce, adding sweetness without being chunky. And garlic? The more, the merrier, in my book! They lay the essential flavor base for our sauce, building layers of savory goodness that make this dish sing.
  • 1/2 cup sun-dried tomatoes in oil, drained and chopped: My absolute favorite part of this whole dish! Sun-dried tomatoes are little bursts of concentrated, sweet-tart umami. Draining them from the oil is key, but don't rinse them completely you want some of that infused flavor. They add such a gorgeous color and depth to the Low Carb Tuscan chicken sauce, it's just divine.
  • 1 1/2 cups low-sodium chicken broth: This is where the magic happens for our velvety sauce! Using low-sodium broth gives you control over the saltiness, which is super important when you're reducing it. It’s going to mingle with all those savory bits in the pan, deglazing and creating a rich, flavorful base before we add any creaminess. It’s essential for that perfect consistency.

Crafting Low Carb Tuscan Chicken: Your Step-by-Step Guide

Step 1: Roast Spaghetti Squash:
First things first, get that spaghetti squash going! Halve it, scoop out the seeds, drizzle with a little olive oil, salt, and pepper, then pop it cut-side down on a baking sheet. It’ll roast away, getting tender and sweet, creating those perfect noodle-like strands while you work on the rest of your Low Carb Tuscan Chicken. I love how hands-off this step is, it's a game-changer for meal timing!
Step 2: Prepare Chicken Medallions:
Now, let’s get our chicken ready for its big moment! Slice those chicken breasts horizontally into thinner medallions about 1/2 inch thick. This helps them cook evenly and quickly. Pat them super dry with paper towels, this is crucial for a good sear! Season generously with oregano, garlic powder, salt, and pepper. You want that flavor deep in the chicken, making every bite of this Low Carb Tuscan Chicken amazing.
Step 3: Sear Golden Chicken:
Heat that 2 tbsp of olive oil in a large skillet over medium-high heat until it shimmers. Now, carefully lay your seasoned chicken medallions in a single layer, making sure not to overcrowd the pan. We're looking for a beautiful golden-brown crust, about 3-4 minutes per side. Don't rush it! Once done, remove the chicken to a plate. Those browned bits left in the pan? Pure gold for our sauce!
Step 4: Sauté Tuscan Aromatics:
Reduce the heat to medium and add the remaining 1 tbsp of olive oil to the skillet. Toss in your finely diced onion and cook until it softens and becomes translucent, about 3-5 minutes. Then, add your minced garlic and chopped sun-dried tomatoes. Sauté for another minute until fragrant. Oh, that smell! This is where the true Tuscan magic starts to build, creating the aromatic base for your incredible Low Carb Tuscan Chicken.
Step 5: Simmer Velvety Sauce:
Pour in the low-sodium chicken broth, scraping up all those delicious browned bits from the bottom of the pan that’s called deglazing, and it’s flavor town! Let it come to a gentle simmer and reduce slightly, maybe 5-7 minutes. This concentrates the flavors and thickens it just a touch. This rich, savory broth is going to become the velvety, dreamy sauce that coats every piece of your Low Carb Tuscan Chicken.
Step 6: Combine & Garnish:
Now for the grand finale! Carefully return the seared chicken medallions back into the simmering sauce. Let them warm through for just a minute or two, soaking up all that incredible flavor. Taste and adjust seasonings if needed. Serve immediately over your roasted spaghetti squash, and don't forget a sprinkle of fresh parsley or basil if you have it. It just brightens everything up, making this dish look as good as it tastes!

Honestly, there's something so satisfying about bringing this dish together. The sizzle of the chicken, the fragrant garlic and onion, then watching that broth transform into a rich sauce… it’s a little kitchen symphony. It feels like a warm hug on a plate, especially after a long day. This Low Carb Tuscan Chicken isn't just food, it's a moment of pure comfort and culinary joy for me.

Keeping Your Low Carb Tuscan Chicken Fresh: Storage Secrets

Okay, so you’ve got leftovers? High five! This dish, especially the Low Carb Tuscan Chicken, actually tastes even better the next day as the flavors really meld. Let it cool completely before transferring it to an airtight container. It’ll keep beautifully in the fridge for up to 3-4 days. I’ve made the mistake of putting warm food straight into the fridge before, and it can sometimes make things a bit soggy or just not cool properly. When reheating, I usually pop it in the microwave for a couple of minutes, or gently warm it on the stovetop with a splash of extra broth if it seems a little thick. Don't let those delicious leftovers go to waste!

Swapping Ingredients in Your Low Carb Tuscan Chicken

I've played around with this recipe so many times, it's wild! If chicken breasts aren't your jam, boneless, skinless thighs work wonders for this Low Carb Tuscan Chicken too they stay even juicier. No spaghetti squash? Cauliflower rice is a fantastic low-carb alternative, or even some steamed green beans. For the sun-dried tomatoes, if you're out, a little roasted red pepper can give you a similar sweet-smoky vibe, though it won't be quite the same. And if you're not strictly low-carb, feel free to add a splash of heavy cream at the end for an even richer sauce! I've tried it, and it's glorious.

Serving Up Low Carb Tuscan Chicken: My Favorite Pairings

While the spaghetti squash is the star base for our Low Carb Tuscan Chicken, don't be afraid to mix things up! I sometimes serve it alongside a crisp, peppery arugula salad with a light vinaigrette the freshness cuts through the richness beautifully. If you're feeling a bit cheeky and not strictly low-carb, a piece of crusty garlic bread for dipping into that amazing sauce is a revelation. For extra veggies, a side of steamed broccoli or sautéed spinach would be perfect. And honestly, a glass of crisp white wine, like a Pinot Grigio, just completes the whole Italian experience. Bellissimo!

The Roots of Low Carb Tuscan Chicken: A Little History

Tuscan chicken, at its heart, is all about celebrating the simple, fresh flavors of the Tuscan region in Italy. Think sun-drenched hills, olive groves, and ingredients like sun-dried tomatoes, garlic, and herbs. While this specific Low Carb Tuscan Chicken recipe is a modern, health-conscious twist, it still pays homage to that rustic, comforting Italian cooking style. It's not some ancient, revered dish, but rather a testament to how those classic Italian flavors can be adapted and enjoyed in new ways. It reminds me of the warmth and heartiness of Italian home cooking, even if it's my own little interpretation.

So there you have it, friends! My absolute favorite Low Carb Tuscan Chicken recipe, perfected through many kitchen adventures.

Burning Questions About Low Carb Tuscan Chicken? FAQs Answered!

Can I use frozen chicken for this recipe?

You totally can, but make sure it's completely thawed and patted super dry before slicing and seasoning. Frozen chicken holds a lot of water, and that'll mess with your sear. Trust me, for the best Low Carb Tuscan Chicken, fresh or fully thawed is the way to go!

How do I get my spaghetti squash to 'noodle' perfectly?

The trick is not to overcook it! Roast it until it's tender but still has a slight bite. Once cooled a bit, use a fork to scrape from the edges inwards. If it's too soft, it'll be mushy, not noodle-y. Practice makes perfect, hon!

Can I make this dish dairy-free?

You can, for sure! Instead of the heavy cream (if you add it), try a dairy-free cream alternative or even a little unsweetened coconut milk for richness. The base sauce is already dairy-free, so it's an easy swap if you skip any optional cream.

My sauce isn't thick enough, what went wrong?

No worries, it happens! It usually means the broth didn't reduce quite enough. Just let it simmer a bit longer on medium-low heat. You can also mix a teaspoon of arrowroot powder with a tablespoon of cold water, stir it in, and let it simmer for another minute to thicken.

What if I don't like sun-dried tomatoes?

Oh, that's okay! You could try roasted red peppers for a similar sweetness and color, or even some fresh cherry tomatoes halved and added at the end. It won't be exactly the same "Tuscan" flavor profile, but it'll still be delicious!

05 2 tbsp olive oil

→ Velvety Tuscan Sauce

06 1 tbsp olive oil
07 1 small yellow onion, finely diced
08 4 cloves garlic, minced
09 1/2 cup sun-dried tomatoes in oil, drained and chopped
10 1 1/2 cups low-sodium chicken broth
11 1/2 cup heavy cream
12 1/4 cup grated Parmesan cheese
13 1/4 tsp red pepper flakes (optional)

→ Roasted Spaghetti Squash & Fresh Greens

14 1 medium spaghetti squash (about 2 1/2 lbs)
15 5 oz fresh spinach
16 2 tbsp fresh basil, chopped, for garnish

Instructions

Step 01

Preheat oven to 400°F. Carefully cut 1 medium spaghetti squash (about 2 1/2 lbs) in half lengthwise, scoop out seeds. Drizzle cut sides with a little olive oil, season with salt and pepper. Place cut-side down on a baking sheet. Roast for 35-40 minutes until tender. This is the base for your Delicious Low Carb Tuscan Chicken and Spaghetti Squash.

Step 02

While squash roasts, slice 1 1/2 lbs boneless, skinless chicken breasts horizontally into thinner medallions. Season generously with 1/2 tsp dried oregano, 1/4 tsp garlic powder, salt, and freshly ground black pepper to taste.

Step 03

Heat 2 tbsp olive oil in a large skillet over medium-high heat. Add chicken medallions in a single layer, cooking in batches if necessary, for 3-4 minutes per side until golden brown and cooked through. Remove chicken from skillet and set aside.

Step 04

In the same skillet, add 1 tbsp olive oil. Sauté 1 small yellow onion, finely diced, for 3-4 minutes until softened. Add 4 cloves garlic, minced, 1/2 cup sun-dried tomatoes, drained and chopped, and 1/4 tsp red pepper flakes (optional). Cook for 1 minute until fragrant.

Step 05

Pour in 1 1/2 cups low-sodium chicken broth, scraping up any browned bits. Bring to a simmer, then stir in 1/2 cup heavy cream and 1/4 cup grated Parmesan cheese. Cook for 3-5 minutes until the sauce thickens slightly. Stir in 5 oz fresh spinach until wilted. This velvety sauce is key to your Delicious Low Carb Tuscan Chicken and Spaghetti Squash.

Step 06

Return the cooked chicken medallions to the skillet with the sauce, tossing to coat. Once spaghetti squash is tender, use a fork to scrape out the strands. Serve the Delicious Low Carb Tuscan Chicken and Spaghetti Squash over the roasted spaghetti squash, garnished with 2 tbsp fresh basil, chopped.

Notes

  1. Don't overcrowd the pan when searing the chicken, cook in batches to ensure a beautiful golden crust. Overcrowding steams the chicken instead of searing it.
  2. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave.
  3. For an extra boost of veggies, consider adding sliced mushrooms or bell peppers to the sauce along with the onion.
  4. A sprinkle of extra Parmesan cheese and a side salad with a light vinaigrette would complement this dish perfectly.
