Keto Tuscan chicken — a creamy, cheesy one-pan dinner ready in 30 minutes

You know those recipes that look like they came out of a restaurant kitchen but actually took you less than half an hour in your own home? This keto Tuscan chicken is exactly that. The kind of dish you put on the table and watch people's faces change when they take the first bite.

I came up with this one on a night when I had chicken, a handful of cherry tomatoes, some broccoli, and absolutely no interest in doing anything complicated.

Twenty minutes of actual cooking later, I had a pan of something so creamy, so cheesy, and so deeply flavorful that it became an immediate weekly staple. My family thought I had spent the whole afternoon on it. I did not correct them.

The best part? One pan. Thirty minutes. Under 8 grams of net carbs per serving. If you're eating keto and you've been stuck in a chicken-and-salad rut, this is the recipe that gets you out of it. Let's cook.

Why you'll love this recipe

• One pan, minimal cleanup — Everything happens in a single skillet. The sauce, the chicken, the vegetables, the melted cheese on top — all in one pan. Your kitchen will barely know you cooked in it.
• Ready in 30 minutes flat — This is a genuine weeknight dinner solution. From cold ingredients to hot food on the table in half an hour.
• That creamy Tuscan sauce — Rich, garlicky, slightly tangy from the tomatoes, and absolutely coating every single piece of chicken and vegetable in the pan. It is the star of the show.
• Melted cheese finish — Because everything is better when you melt cheese over the top at the end. This is a fact.
• Low carb and keto friendly — Under 8g net carbs per serving, high in protein, and filling enough that you won't be hunting for snacks an hour later.
• Adaptable — Swap the vegetables, change the cheese, add spinach or sun-dried tomatoes. The base recipe is incredibly flexible and works with whatever you have on hand.

Ingredients with key notes

For the chicken:

• 1.5 lbs boneless skinless chicken breasts, cut into bite-sized chunks — Cutting the chicken into chunks rather than leaving it whole speeds up the cook time significantly and gives you more surface area to sear, which means more flavor. Pat them dry before seasoning for the best sear.
• 1 tsp garlic powder
• 1 tsp smoked paprika — This gives the chicken a subtle warmth and color before it even hits the sauce.
• 1/2 tsp onion powder
• Salt and black pepper to taste
• 2 tbsp olive oil — For searing the chicken.

For the Tuscan sauce:

• 4 garlic cloves, minced — Fresh garlic is non-negotiable in a Tuscan sauce. The jarred stuff just does not deliver the same punch.
• 3/4 cup heavy cream — This is the base of your sauce. It gives you that rich, velvety texture that makes Tuscan chicken what it is. Do not substitute with milk or half and half — you need the fat content for the sauce to come together properly.
• 1/2 cup chicken broth — Low sodium. This loosens the sauce slightly and adds savory depth without making it too heavy.
• 2 tbsp tomato paste — Adds a rich, slightly sweet tomato base to the sauce that ties everything together.
• 1 tsp dried Italian seasoning
• 1/2 tsp red pepper flakes — Optional, but highly recommended. Just enough heat to keep things interesting.
• Salt and pepper to taste

Vegetables:

• 1 cup cherry tomatoes — These burst during cooking and release their juices into the sauce, adding a fresh, slightly acidic brightness that balances the richness of the cream perfectly.
• 2 cups broccoli florets — Cut them small so they cook through in the pan without needing extra time. They add texture, color, and nutrition to an already solid dish.
• 1 cup shredded mozzarella cheese — For melting over the top at the end. You can also use a mix of mozzarella and parmesan for a sharper, more complex finish.

Step-by-step instructions

Step 1: Season and sear the chicken

Pat the chicken chunks completely dry with paper towels — this is your first step toward a good sear and you don't want to skip it. Season all over with garlic powder, smoked paprika, onion powder, salt, and black pepper.

Heat olive oil in a large skillet over medium-high heat until shimmering. Add the chicken pieces in a single layer — work in batches if your pan isn't big enough to fit them without crowding. Sear for 3-4 minutes per side until golden brown. The chicken doesn't need to be fully cooked through at this stage. Transfer to a plate and set aside.

Step 2: Saute the vegetables

In the same skillet, reduce the heat to medium. Add the broccoli florets and cook for 3-4 minutes, stirring occasionally, until they start to turn bright green and pick up a little color from the pan. Add the cherry tomatoes and cook for another 2 minutes until they begin to soften and blister. You'll notice some of them starting to burst — that's exactly what you want. All those tomato juices going into the pan are pure flavor.

Step 3: Build the Tuscan sauce

Push the vegetables to the sides of the pan and add the minced garlic to the center. Cook for 60 seconds, stirring constantly, until fragrant. Add the tomato paste and stir it into the garlic, letting it cook for another minute.

Pour in the chicken broth and use a wooden spoon to scrape up any browned bits from the bottom of the pan. Add the heavy cream, Italian seasoning, and red pepper flakes. Stir everything together and let the sauce come to a gentle simmer. Cook for 3-4 minutes, stirring occasionally, until it thickens slightly.

Step 4: Add the chicken back in

Return the seared chicken pieces to the skillet, nestling them into the sauce and vegetables. Make sure everything is well coated in that creamy Tuscan sauce. Reduce the heat to medium-low and let everything simmer together for 5-6 minutes until the chicken is cooked through and the sauce has thickened to your liking. Taste and adjust seasoning.

Step 5: Add the cheese

Sprinkle the shredded mozzarella evenly over the top of the entire pan. Cover the skillet with a lid and let it sit for 2-3 minutes over low heat until the cheese is fully melted and gooey. If you want the cheese to brown slightly on top, slide the whole skillet under the broiler for 2-3 minutes instead — keep a close eye on it.

Step 6: Serve

Take the lid off, take a moment to appreciate what you just made in under thirty minutes, and serve immediately straight from the pan. Garnish with fresh basil or a pinch of red pepper flakes if you have them. This dish is best eaten hot while the sauce is still silky and the cheese is still melted.

Serving suggestions

• Over mashed cauliflower — The creamy Tuscan sauce is incredible spooned over a bed of buttery mashed cauliflower. This is my personal favorite way to serve it.
• With zucchini noodles — For a pasta-style experience that keeps it fully keto, zucchini noodles are the move. The sauce coats them beautifully.
• Over cauliflower rice — A lighter option that soaks up the sauce without adding significant carbs.
• With a simple green salad — If you want to keep things light, a crisp green salad on the side is all this dish needs. The chicken and sauce are rich enough to carry the meal on their own.
• With roasted asparagus — The slight bitterness of roasted asparagus works beautifully as a contrast to the richness of the Tuscan sauce.

Storage tips

Refrigerator: Let the dish cool completely before transferring to an airtight container. Store in the fridge for up to 4 days. The sauce may thicken as it sits — that's normal.

Freezer: This dish can be frozen, though cream-based sauces can sometimes separate slightly when thawed. To minimize this, let it cool completely, transfer to a freezer-safe container, and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

Reheating: Reheat on the stovetop over medium-low heat, adding a splash of chicken broth or heavy cream to loosen the sauce back up as it warms. Stir gently and heat until warmed through. Individual portions can be microwaved in 90-second intervals, stirring between each. Add a small splash of broth if the sauce looks too thick.

A quick word before you go

Eating keto doesn't mean eating boring. It doesn't mean spending your dinner hour staring at a plain chicken breast wondering where the flavor went. This Tuscan chicken is proof of that — creamy, cheesy, packed with vegetables, and done in the time it would take you to order and wait for takeout.

One pan. Thirty minutes. A dinner that feels like a treat even though it's completely on track with your goals.

That's the kind of cooking I want to share with you here at Recipes By Kip. Food that makes you feel good about what you're eating and genuinely excited to sit down at the table.

Make this one tonight. I think you're going to love it.

With gratitude, Kip.
