🫑 Keto Stuffed Peppers With Ground Sausage and Cheese
There are some dinners that just feel like home, and these Keto Stuffed Peppers With Ground Sausage and Cheese are definitely one of them.
I first made these on a weekend when I wanted something comforting and cheesy without spending hours in the kitchen. I had some ground sausage in the refrigerator, a few bell peppers waiting to be used, and, of course, plenty of cheese. That combination turned into one of those dinners that disappears from the table surprisingly fast.
The sausage gives the filling so much flavor that you don’t need a complicated list of ingredients. The peppers become tender and slightly sweet as they bake, while the cheese melts over the top into that golden, bubbly layer we all love.
And the best part? There’s no rice or breadcrumbs hiding in the filling. Just flavorful sausage, vegetables, seasonings, and lots of cheesy goodness.
❤️ Why You’ll Love These Keto Stuffed Peppers
- Low-carb and satisfying: No rice, pasta, or breadcrumbs.
- Packed with flavor: Italian-style sausage does most of the heavy lifting.
- Extra cheesy: Cheese goes both inside and on top.
- Easy weeknight dinner: Most of the work happens in one skillet.
- Family-friendly: Even people who aren’t following keto usually love these.

👩🍳 How to Make Keto Stuffed Peppers
1. Prepare the Peppers
Preheat your oven to 375°F (190°C).
Wash the bell peppers and cut them in half lengthwise. Remove the seeds and white membranes.
Place the pepper halves cut-side up in a lightly greased baking dish.
If your peppers are especially large and firm, you can pre-bake them for about 8–10 minutes before adding the filling. This gives them a head start and makes the finished peppers extra tender.
2. Brown the Sausage
Heat the olive oil in a large skillet over medium heat.
Add the ground Italian sausage and cook for about 5–7 minutes, breaking it apart with a wooden spoon as it browns.
If there’s a lot of excess grease, carefully drain some of it.
3. Add the Onion and Garlic
Add the diced onion to the skillet.
Cook for 3–4 minutes, until the onion begins to soften.
Add the minced garlic and cook for another 30–60 seconds, just until fragrant.
This little step makes such a difference. The garlic and sausage together create that irresistible savory smell that makes everyone start wandering into the kitchen asking, “What’s for dinner?”
4. Season the Filling
Stir in the tomato sauce, Italian seasoning, smoked paprika, salt, and black pepper.
Let everything simmer together for about 3–4 minutes.
Taste the mixture and adjust the seasoning if needed.
5. Make It Cheesy
Remove the skillet from the heat.
Stir in 1 cup mozzarella and 1/2 cup cheddar until the cheese starts melting into the sausage mixture.
The filling should be thick, creamy, savory, and easy to spoon into the peppers.
6. Stuff the Peppers
Spoon the sausage mixture evenly into each pepper half.
Don’t be afraid to pile the filling up slightly. As the cheese melts, everything settles into the peppers.
Sprinkle the remaining mozzarella and Parmesan over the tops.
7. Bake
Cover the baking dish loosely with aluminum foil and bake for 20 minutes.
Remove the foil and continue baking for another 10–15 minutes, until the peppers are tender and the cheese is melted, bubbling, and lightly golden.
For an extra-browned cheese topping, place the peppers under the broiler for 1–2 minutes at the end. Watch them carefully because cheese can go from golden to burnt very quickly.
Let the peppers rest for about 5 minutes before serving.
🧀 The Best Cheese for Stuffed Peppers
Mozzarella is my favorite here because it melts beautifully, but you have plenty of options.
Try:
- Cheddar for a stronger, richer flavor
- Monterey Jack for an ultra-creamy melt
- Provolone for an Italian-inspired flavor
- Gouda for something slightly smoky
- Parmesan for a salty golden crust
- Colby Jack for a mild, family-friendly option
A combination of mozzarella and cheddar is hard to beat.
🌶️ Easy Variations
Spicy Sausage Stuffed Peppers
Use hot Italian sausage and add a pinch of crushed red pepper flakes.
Creamy Sausage Peppers
Stir 2–3 tablespoons of softened cream cheese into the cooked sausage mixture before stuffing the peppers.
Pizza-Style Stuffed Peppers
Add a little extra sugar-free marinara, mozzarella, Italian seasoning, and chopped pepperoni.
Bacon Cheeseburger Version
Swap the Italian sausage for ground beef and add cooked bacon, cheddar, mustard, and a little onion.
Mushroom & Sausage
Sauté 1 cup sliced mushrooms with the onions before adding the sausage.
Green Pepper Version
Use green bell peppers if you prefer a slightly less sweet, more savory flavor.
🥗 What to Serve With Keto Stuffed Peppers
These peppers are filling enough to serve as a complete meal, but I love adding a simple side.
Try them with:
- Garlic butter broccoli
- Roasted cauliflower
- Sautéed spinach
- Cauliflower rice
- Simple green salad
- Cucumber salad
- Steamed green beans
- Garlic mushrooms
- Avocado salad
If I’m making these on a busy weeknight, a quick green salad is usually all I need.
💡 Tips for Perfect Stuffed Peppers
Choose peppers that stand up well.
Look for large peppers with relatively flat bottoms. If you’re using whole peppers rather than halves, trim just a tiny bit from the bottom if necessary so they stand upright.
Don’t overcook the sausage.
Brown it until cooked through, but don’t let it become dry before it goes into the oven.
Don’t skip the cheese inside.
Adding cheese directly to the filling helps bind everything together and makes every bite creamy.
Use freshly shredded cheese when possible.
It usually melts more smoothly than many pre-shredded varieties.
Don’t over-bake the peppers.
You want them tender but still sturdy enough to hold the filling.
Let them rest.
Five minutes gives the filling time to settle, which makes the peppers easier to serve.
🥘 Can I Make These Ahead?
Absolutely.
Prepare the sausage filling, stuff the peppers, cover the baking dish, and refrigerate for up to 24 hours.
When you’re ready to cook them, take the dish out of the refrigerator while the oven preheats. You may need to add a few extra minutes to the baking time because the peppers and filling will be cold.
🧊 How to Store Leftovers
Store leftover stuffed peppers in an airtight container in the refrigerator for up to 3–4 days.
For the best texture, reheat them in the oven or air fryer rather than microwaving them for too long.
Oven
Reheat at 350°F (175°C) for about 10–15 minutes, or until hot.
Air Fryer
Heat at 350°F for approximately 5–8 minutes.
Microwave
Microwave individual portions for 1–2 minutes, checking halfway through.
❄️ Can You Freeze Stuffed Peppers?
Yes.
Let the cooked peppers cool completely, then place them in an airtight freezer-safe container.
Freeze for up to 2–3 months for the best quality.
Thaw overnight in the refrigerator and reheat at 350°F until heated through.
For the best texture, I prefer freezing the assembled but uncooked peppers when possible, then thawing them in the refrigerator before baking.
❓ Frequently Asked Questions
Are stuffed peppers keto?
They can be. The main thing is what you put inside them. Traditional stuffed peppers often contain rice or other higher-carb ingredients, while this version uses sausage, cheese, and a sugar-free tomato sauce instead. Similar keto versions use meat, cheese, and peppers without rice.
Can I use ground beef instead of sausage?
Absolutely. Ground beef works beautifully. You may want to add extra Italian seasoning, garlic, and fennel seed to give it some of the flavor that sausage naturally provides.
Can I use ground turkey?
Yes. Ground turkey is leaner, so consider adding a little extra cheese or cream cheese to keep the filling moist.
Do I need to boil the peppers first?
No. You can bake them directly after stuffing. If you prefer very soft peppers, pre-bake the halves for 8–10 minutes before filling them.
Can I use whole peppers instead of halves?
Yes. Cut off the tops, remove the seeds and membranes, then stand the peppers upright in a baking dish. They may need a little extra baking time.
What sausage is best?
Mild or hot Italian sausage works especially well. Breakfast sausage can also work if you prefer a more savory breakfast-style flavor.
Always check the label if you’re following keto, because some prepared sausages contain added sugars or starches.
Can I make these without tomato sauce?
Yes. Simply leave it out and replace it with a few tablespoons of chicken broth or heavy cream. You can also make a creamy cheese-based filling with cream cheese.
How do I prevent watery stuffed peppers?
Don’t add too much sauce, and make sure the sausage filling isn’t excessively greasy. Letting the peppers rest for a few minutes after baking also helps the filling set.
