• In a skillet over medium heat, sauté onion and garlic until fragrant. Add ground beef and cook until browned, breaking into pieces.
• Stir in cauliflower rice, tomato paste, Italian seasoning, salt, and pepper. Cook until cauliflower softens and mixture is combined. Remove from heat and let cool 2–3 min.
• Stir in ¾ cup mozzarella and ¼ cup cheddar until just melted into filling.
• Spoon the beef mixture into each pepper, filling to the top.

Notes

Use higher‑fat beef (80/20 or 70/30) so filling stays juicy. Avoid starchy fillers—cauliflower rice keeps it keto. Prevent soggy peppers by pre‑cooking them briefly. Add cheese mid‑cook for the perfect bubbly, golden top.

Keto Ingredients Breakdown for Beef-Stuffed Bell Peppers

Choosing Low-Carb Ingredients Without Sacrificing Taste

When preparing beef-stuffed bell peppers in the air fryer, the secret to keeping it keto is all about smart ingredient swaps. Skip the rice, breadcrumbs, or starchy fillers. Instead, stick to naturally low-carb components like:

• Grass-fed ground beef – Rich in protein and fat
• Cauliflower rice – A perfect filler substitute with only 2g net carbs per ½ cup
• Full-fat cheeses – Shredded mozzarella, cheddar, or pepper jack
• Low-carb tomato paste or crushed tomatoes – Watch for added sugars
• Onions and garlic (in moderation) – Great flavor for minimal carbs

Always check labels for sneaky sugars and starches in packaged sauces or spice blends. Keeping it clean ensures your stuffed peppers stay fully keto-approved.

Best Ground Beef Cuts for Keto Air Fryer Recipes

Fat is your friend on keto. Opt for 80/20 or even 70/30 ground beef. Lean beef dries out faster, especially in an air fryer. The extra fat keeps your filling juicy and flavorful.

Cheeses That Melt Best and Are Keto-Compliant

Not all cheeses melt equally and for stuffed peppers, you want the good melt. Stick to:

• Mozzarella – Creamy and classic
• Cheddar – Sharp flavor and melty texture
• Pepper Jack – Adds a spicy kick
• Provolone – Mild and stretchy when hot

Avoid shredded cheese blends with anti-caking agents, which can prevent smooth melting.
