Indulge in a delicious and healthy meal with these keto stuffed bell peppers. Perfect for those following a low-carb diet, this dish is packed with flavor and nutrients. The combination of ground beef, cauliflower rice, and melted cheese creates a satisfying and hearty meal that the whole family will love.
If you're not familiar with cauliflower rice, it's simply finely chopped cauliflower that resembles rice grains. You can find it in the produce section or frozen aisle of most supermarkets. Additionally, make sure to pick up bell peppers that are firm and have a vibrant color, as they will hold up better during baking.

Ingredients For Keto Stuffed Bell Peppers Recipe
Bell peppers: These are the main vessels for the stuffing. Choose firm and colorful ones.
Ground beef: Provides the protein and savory base for the stuffing.
Cauliflower rice: A low-carb alternative to traditional rice, adding texture and volume.
Shredded cheese: Melts on top, adding a creamy and rich flavor.
Tomato sauce: Adds moisture and a tangy taste to the stuffing mixture.
Garlic powder: Enhances the overall flavor with a hint of garlic.
Onion powder: Adds a subtle onion flavor without the need for fresh onions.
Salt: Essential for seasoning and bringing out the flavors.
Black pepper: Adds a touch of heat and depth to the stuffing.
Technique Tip for Keto Stuffed Bell Peppers
When preparing the bell peppers, consider blanching them in boiling water for 2-3 minutes before stuffing. This will help soften the peppers and reduce the baking time, ensuring they come out perfectly tender.

How to Store or Freeze This Dish
- Allow the stuffed bell peppers to cool completely after baking. This helps prevent condensation, which can make the peppers soggy.
- Transfer the cooled bell peppers to an airtight container. If stacking, place a piece of parchment paper between layers to avoid sticking.
- Store the container in the refrigerator for up to 4 days. Reheat in the oven at 350°F (175°C) for about 15 minutes or until heated through.
- For freezing, wrap each stuffed pepper individually in plastic wrap or aluminum foil. This ensures they maintain their shape and prevents freezer burn.
- Place the wrapped peppers in a freezer-safe bag or container. Label with the date to keep track of freshness.
- Freeze for up to 3 months. When ready to eat, thaw in the refrigerator overnight.
- Reheat thawed stuffed bell peppers in the oven at 350°F (175°C) for 20-25 minutes, or until heated through and the cheese is bubbly.
- For a quicker option, microwave the thawed peppers on medium power for 3-5 minutes, checking halfway to ensure even heating.
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. Heat for about 20-25 minutes or until the peppers are warmed through and the cheese is melted.
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. Continue heating in 1-minute increments until thoroughly warmed.
Stovetop Method: Slice the stuffed bell peppers into halves or quarters for even heating. Place them in a skillet over medium heat with a splash of tomato sauce or broth to keep them moist. Cover and heat for about 10 minutes, stirring occasionally, until the peppers and filling are hot.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the stuffed bell peppers in the air fryer basket, making sure they are not overcrowded. Heat for 5-7 minutes, checking halfway through to ensure they are warming evenly. The cheese should be bubbly and the peppers tender.
Sous Vide Method: If you have a sous vide machine, set it to 140°F (60°C). Place the stuffed bell peppers in a vacuum-sealed bag or a ziplock bag using the water displacement method. Submerge in the water bath for about 45 minutes to an hour. This method ensures the peppers are evenly heated without drying out.
