A Low-Carb, High-Fiber Meal Prep Favorite
Some recipes are built for flexibility. This one-skillet Italian chicken in tomato-mushroom sauce is one of them. It’s deeply flavorful, packed with vegetables, and works with whatever you have on hand. Whether you want to switch up the protein, adjust the vegetables, or tweak the flavors, this recipe adapts while staying low-carb, high-fiber, and rich in heart-healthy fats.
How This Recipe Works
At its core, this dish is:
✅ A protein (chicken, tofu, or even eggs)
✅ A tomato-based mushroom sauce (simple, savory, and full of umami)
✅ A base to soak up the sauce (riced cauliflower, sautéed greens, or roasted eggplant)
By adjusting these elements, you can make it again and again—without it ever feeling repetitive.
Base Recipe: Italian Chicken & Tomato-Mushroom Sauce
🥣 Servings: 3
🕒 Total Time: 35 minutes
🔥 Cook Time: 30 minutes
💡 Net Carbs: ~8-10g per serving
🛒 Ingredients
Protein (Choose One)
- Chicken thighs (boneless, skinless) – 3 pieces (~12 oz total) (rich & tender)
- Chicken breast – 1 large (~10 oz total) (leaner, cooks faster)
- Tofu (extra firm, pressed, cubed) – 10 oz (plant-based alternative)
- Eggs – 3 soft-boiled or poached eggs (for a lighter variation)
Tomato-Mushroom Sauce
- 1 tbsp olive oil (for healthy fats)
- ½ small red onion, finely chopped
- 2 cloves garlic, minced
- 1 ½ cups frozen mixed mushrooms, roughly chopped if large
- 1 cup cherry tomatoes, halved (or ½ cup canned diced tomatoes for a saucier version)
- ½ tsp dried oregano
- ½ tsp dried thyme
- ¼ tsp red pepper flakes (optional, for heat)
- 1 tbsp red wine vinegar (or balsamic vinegar for sweetness)
- ½ cup chicken broth or water
- Salt & black pepper, to taste
- 1 ½ cups fresh spinach, roughly chopped
Serving Base (Choose One)
- 2 cups frozen riced cauliflower (classic low-carb base)
- 1 small globe eggplant, cubed into ¾-inch pieces and roasted (hearty and saucy)
- 2 cups sautéed greens (for extra fiber)
👩🍳 Instructions
Step 1: Sear the Protein
- Heat 1 tbsp olive oil in a large skillet over medium-high heat.
- Season chicken thighs (or tofu) with salt and black pepper.
- Sear for 3-4 minutes per side until lightly golden. (If using tofu, sear until golden on all sides.)
- Remove from the pan and set aside.
📌 If using eggs, boil or poach separately and set aside for serving.
Step 2: Build the Sauce
- In the same skillet, lower heat to medium and add red onion. Sauté for 2 minutes until softened.
- Stir in garlic, mushrooms, oregano, thyme, and red pepper flakes. Cook for 3-4 minutes, stirring occasionally.
- Add cherry tomatoes (or canned tomatoes) and cook for 2 minutes until they start to break down.
- Deglaze the pan with red wine vinegar, scraping up any browned bits.
- Pour in ½ cup broth or water and return the seared protein to the skillet.
- Cover and simmer for 12-15 minutes, flipping chicken halfway, until cooked through.
- In the last 2 minutes, stir in chopped spinach and let it wilt.
Step 3: Prepare the Base
- While the sauce simmers, cook your base:
Cauliflower Rice:
- Heat 1 tbsp olive oil over medium heat.
- Add 2 cups frozen riced cauliflower and cook for 5 minutes, stirring.
- Season with salt, black pepper, and 1 tbsp nutritional yeast (for cheesiness).
Eggplant:
- Roast cubed eggplant (¾-inch pieces) at 400°F (200°C) for 20 minutes with olive oil, salt, and pepper.
Sautéed Greens:
- Sauté chopped greens (spinach, kale, or arugula) in olive oil for 2 minutes until wilted.
Step 4: Assemble & Serve
- Divide the base into three bowls.
- Spoon the chicken & sauce over the top.
- Garnish with extra red pepper flakes, a drizzle of olive oil, or a sprinkle of fresh basil.
📌 If using eggs, place one poached or halved boiled egg on top of each serving.
💡 Meal Prep & Storage
- Store components separately in airtight containers to maintain texture and freshness. Keep the chicken and sauce together, but store the base (cauliflower rice, roasted eggplant, or greens) separately.
- Reheat gently on the stovetop or microwave. Combine just before serving.
- Store in airtight containers in the fridge for up to 4 days.
