Low Carb Chicken Alfredo Stuffed Peppers - Creamy, Comforting, and Weeknight-Friendly
Ingredients
Method
- Prep the peppers: Preheat your oven to 400°F (200°C). Slice the bell peppers in half lengthwise and remove seeds and membranes. Drizzle with olive oil, season with salt and pepper, and place cut-side up in a baking dish. Roast for 12–15 minutes until slightly tender but still holding shape.
- Make the Alfredo base: While the peppers roast, melt the butter in a skillet over medium heat. Add garlic and cook 30–60 seconds until fragrant, not browned.
- Add cream and cream cheese: Pour in the heavy cream and whisk in the cream cheese until smooth and slightly thickened, 2–3 minutes. Keep the heat gentle to prevent breaking.
- Stir in cheese and seasoning: Add Parmesan, nutmeg, Italian seasoning, and a pinch of salt and pepper. Whisk until the sauce is velvety and coats the back of a spoon. If too thick, splash in a little more cream or water.
- Fold in chicken: Add the cooked chicken to the sauce and stir to combine. Let it warm through for 1–2 minutes. Taste and adjust seasoning.
- Stuff the peppers: Spoon the creamy chicken mixture into each roasted pepper half. Don’t overfill—aim for level and tidy mounds.
- Top and bake: Sprinkle with extra Parmesan and the mozzarella. Return the dish to the oven and bake for 10–12 minutes, until the cheese is melted and lightly golden.
- Finish and serve: Let the peppers rest for 5 minutes so the filling sets. Garnish with chopped parsley or chives. Serve warm.
Why This Recipe Works
- All the Alfredo flavor, fewer carbs: Swapping pasta for bell peppers keeps things light without losing that creamy, cheesy satisfaction.
- Fast-cook shortcuts: Using rotisserie chicken or leftover cooked chicken slashes prep time and keeps the filling juicy.
- Balanced texture: Roasting the peppers first keeps them tender but not mushy, and baking at the end melts everything together.
- One-pan friendly: The sauce comes together in a single skillet, and the whole dish bakes in one dish for easy cleanup.
- Make-ahead ready: You can assemble in advance and bake when you’re ready to eat.
What You’ll Need
- 4 large bell peppers (any color; red or yellow are sweetest)
- 2 cups cooked chicken, shredded or diced (rotisserie works great)
- 2 tablespoons butter
- 3 cloves garlic, minced
- 1 cup heavy cream (or half-and-half for lighter sauce; see pitfalls)
- 3 ounces cream cheese, softened and cubed
- 1 cup freshly grated Parmesan (plus extra for topping)
- 1/2 cup shredded mozzarella (for topping)
- 1 tablespoon olive oil
- 1/4 teaspoon nutmeg (optional but classic in Alfredo)
- 1/2 teaspoon Italian seasoning (or a mix of dried basil and oregano)
- Salt and black pepper to taste
- Fresh parsley or chives, chopped, for garnish
Instructions
- Prep the peppers: Preheat your oven to 400°F (200°C). Slice the bell peppers in half lengthwise and remove seeds and membranes.
Drizzle with olive oil, season with salt and pepper, and place cut-side up in a baking dish. Roast for 12–15 minutes until slightly tender but still holding shape.

Keep the heat gentle to prevent breaking.

- Fold in chicken: Add the cooked chicken to the sauce and stir to combine.

How to Store
- Refrigerate: Cool completely, then store in an airtight container for up to 4 days.
- Reheat: Warm in a 350°F (175°C) oven for 12–15 minutes, or microwave in 45-second bursts until hot.
Add a spoonful of water and cover if reheating in the oven to keep things moist.
- Freeze: Freeze baked and cooled peppers for up to 2 months. Thaw overnight in the fridge, then reheat in the oven until hot and bubbly.
Why This is Good for You
- Lower in carbs: Swapping pasta for peppers keeps net carbs low while adding fiber.
- High in protein: Chicken and cheese make this filling and satisfying, which can help with appetite control.
- Nutrient-dense veggies: Bell peppers bring vitamin C, antioxidants, and color without weighing you down.
- Customizable fats: You control the richness—use heavy cream for keto or lighten it with half-and-half if that suits your goals.
Pitfalls to Watch Out For
- Watery peppers: Skip roasting and you’ll get excess moisture. Pre-roasting drives off water and keeps the filling creamy.
- Broken sauce: Boiling dairy hard can cause separation.
Keep the heat medium-low and whisk steadily.
- Pre-shredded cheese: It often has anti-caking agents that prevent smooth melting. Freshly grate your Parmesan for best texture and flavor.
- Overbaking: Too long in the oven and the peppers go limp. Bake just until the cheese melts and gets a little color.
- Too salty: Parmesan is salty. Taste the sauce before adding extra salt.
Variations You Can Try
- Broccoli Alfredo: Fold in 1 cup of steamed, chopped broccoli with the chicken for extra crunch and greens.
- Spinach and Artichoke: Add a handful of chopped spinach and 1/2 cup diced artichoke hearts to the sauce.
- Bacon Ranch: Stir in 2–3 slices of cooked, crumbled bacon and a teaspoon of dry ranch seasoning.
- Mushroom Lovers: Sauté sliced mushrooms in butter first, then build the sauce in the same pan.
- Pesto Twist: Add 1–2 tablespoons of basil pesto to the Alfredo sauce for a fresh, herby finish.
- Dairy-light version: Use half-and-half and reduce Parmesan to 3/4 cup.
Thicken gently by simmering a minute longer.
- Spicy kick: Add crushed red pepper flakes or a pinch of cayenne to the sauce.
FAQ
Can I make this with raw chicken?
Yes, but cook it first. Dice chicken into small pieces and sauté in olive oil with salt and pepper until cooked through. Then proceed with the sauce and stuffing steps.
What peppers are best for stuffing?
Larger, flatter peppers (like red or yellow bell peppers) work best because they sit well in the baking dish and roast evenly.
Green peppers are fine but less sweet.
How do I keep the sauce from getting grainy?
Use freshly grated Parmesan, keep the heat moderate, and whisk continuously. Add the cheese off the heat or on very low heat so it melts gently.
Is there a non-dairy option?
You can try full-fat coconut milk and a dairy-free Parmesan alternative. The flavor will shift slightly sweeter and less cheesy, but it still makes a rich, satisfying filling.
Can I make these ahead?
Absolutely.
Assemble the stuffed peppers, cover, and refrigerate up to 24 hours. Bake an extra 5–10 minutes since you’re starting from cold.
What should I serve with them?
A simple green salad, roasted asparagus, or sautéed zucchini pairs well. For extra richness, drizzle a little leftover Alfredo sauce on the plate.
How many carbs are in each pepper?
Exact numbers vary by brands and pepper size, but generally expect about 6–9 net carbs per stuffed pepper half.
Check your labels for precise tracking.
Can I use canned chicken?
You can in a pinch. Drain it well and gently fold it into the sauce to avoid breaking it up too much. Rotisserie or leftover roasted chicken has better texture.
What if my filling seems too thick?
Whisk in a splash of cream, chicken broth, or even water until you reach a creamy, scoopable consistency.
Add gradually so it doesn’t get runny.
Can I air fry these?
Yes. Air fry pre-roasted, stuffed peppers at 360°F (182°C) for 6–8 minutes until the cheese is melted and golden. Work in batches if needed.
