Ingredients For Keto Stuffed Bell Peppers Recipe
Bell peppers: These are the vessels for your stuffing. Choose large, firm peppers in any color you prefer.
Ground beef: Provides the protein and main substance of the filling. Opt for a leaner cut to keep it healthier.
Cauliflower rice: A low-carb alternative to traditional rice, adding texture and volume to the stuffing.
**Cheddar or mozzarella cheese: Adds a creamy, melty element to the filling. Choose your favorite or use a mix of both.
Garlic powder: Enhances the flavor with a subtle garlic taste.
Onion powder: Adds a mild onion flavor without the need for chopping fresh onions.
Salt: Essential for seasoning and bringing out the flavors of the other ingredients.
Black pepper: Adds a bit of heat and depth to the overall taste.
Technique Tip for This Recipe
When preparing the bell peppers for stuffing, consider blanching them in boiling water for 2-3 minutes before stuffing. This will help to soften the peppers slightly, ensuring they cook evenly and become tender in the oven. Additionally, for a richer flavor, you can sauté the ground beef with some diced onions and garlic before mixing it with the cauliflower rice and cheese. This step will enhance the overall taste of the filling.

How to Store / Freeze This Dish
Allow the stuffed bell peppers to cool completely before storing. This helps prevent condensation, which can make the peppers soggy.
For short-term storage, place the cooled stuffed bell peppers in an airtight container. They can be kept in the refrigerator for up to 3-4 days.
If you plan to freeze the stuffed bell peppers, wrap each one individually in plastic wrap or aluminum foil. This helps to maintain their shape and prevents freezer burn.
Place the wrapped stuffed bell peppers in a freezer-safe bag or container. Label with the date to keep track of freshness. They can be frozen for up to 2-3 months.
When ready to reheat, thaw the stuffed bell peppers in the refrigerator overnight. This ensures even reheating and maintains the texture.
To reheat, preheat your oven to 350°F (175°C). Place the stuffed bell peppers in a baking dish and cover with aluminum foil. Bake for 20-25 minutes, or until heated through.
Alternatively, you can reheat the stuffed bell peppers in the microwave. Place them on a microwave-safe plate, cover with a microwave-safe lid or another plate, and heat on medium power for 3-5 minutes, checking halfway through.
For an extra touch, sprinkle some additional shredded cheese on top before reheating in the oven. This will give a fresh, melty finish to your stuffed bell peppers.
If you find the bell peppers have become too soft after freezing and reheating, consider serving them with a fresh side salad or some steamed vegetables to balance the texture.
How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the stuffed bell peppers in a baking dish and cover with aluminum foil to prevent them from drying out. Bake for about 20-25 minutes, or until heated through. This method ensures the bell peppers remain tender and the filling is evenly warmed.
Microwave Method: Place the stuffed bell peppers in a microwave-safe dish. Cover with a microwave-safe lid or plastic wrap, leaving a small vent for steam to escape. Heat on medium power for 2-3 minutes, then check the temperature. If needed, continue heating in 30-second increments until thoroughly warmed. This method is quick but may result in slightly softer peppers.
Stovetop Method: Slice the stuffed bell peppers in half to allow for even heating. Place them in a skillet with a splash of water or broth. Cover with a lid and heat over medium-low heat for about 10-15 minutes, or until heated through. This method helps retain moisture and flavor.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the stuffed bell peppers in the basket, ensuring they are not overcrowded. Heat for 5-7 minutes, checking halfway through to ensure they are warming evenly. This method gives a slightly crispy exterior while keeping the inside moist.
Slow Cooker Method: Place the stuffed bell peppers in your slow cooker. Add a small amount of broth or water to the bottom to prevent sticking. Cover and heat on low for 1-2 hours, or until thoroughly warmed. This method is ideal for a hands-off approach and keeps the peppers tender.
