What You’ll Need (Ingredients)
Makes about 6 mini peppers (or 3 large peppers)
- 6 mini orange or yellow peppers (or 3 large orange bell peppers if mini aren’t available)
- 1 lb ground beef (or turkey—see swaps below)
- ½ cup shredded mozzarella (or dairy-free shredded cheese, if needed)
- 1 bag of frozen cauliflower rice
- 1 small onion, finely chopped
- 1 tsp garlic powder
- 1 tsp fajita seasoning
- Salt + pepper to taste
- Olive oil spray (for coating the peppers before tossing them into the air fryer)
- optional: sour cream for topping peppers (or dairy-free version)
Plus, you’ll need a sharp paring knife for carving!

Why This Works for Keto
- Low Carb, High Protein: Bell peppers are surprisingly low in net carbs (~4g per medium pepper), and the beef + cheese offer quality fats and protein.
- Dairy Swap Option: Skip cheese or choose a dairy-free alternative for keto-vegan style. The filling is still flavorful!
- No Rice or Breadcrumbs: It’s all meat, cheese, and veggies—no sneaky starches here.
- Fun and Engaging: Kids love the carving step, and it’s a playful way to sneak in veggies.
Step-by-Step Instructions (Carving + Cooking)
1️⃣ Prep & Preheat
- Preheat oven to 375°F (190°C).
- Air Fryer Method: 400 degrees, 12 mins
- Wash peppers and slice off the tops. If using large peppers, carve cute jack‑o’lantern faces: triangle eyes, a nose, and a toothy grin. Let the kids design their own!
- Prep cauliflower rice based off bag instructions (microwave route is best)
2️⃣ Brown the Meat
- In a skillet over medium heat, sauté chopped onion until softened (2–3 mins).
- Add ground beef and seasonings (garlic powder, fajita seasoning, salt/pepper). Brown until no longer pink.
- Stir in cooked cauliflower rice and half the cheese. Remove from heat.
3️⃣ Stuff the Peppers
- Lightly spray insides of peppers with olive oil (optional).
- Fill them generously with the meat mixture. Top with remaining cheese.
- Place stuffed peppers upright in a baking dish, close-fitting.
4️⃣ Bake & Melt
- Cover with foil and bake 20 minutes.
- Remove foil and bake another 10 minutes, until cheese is golden.
5️⃣ Serve & Enjoy
- Let cool just enough so little hands can handle them.
- Plate them individually or right in the baking dish—spooky vibes intact!



Fun Tips to Involve Your Kids
- Carving Artists: Let them draw or carve faces with adult help—it’s like Halloween crafts with dinner!
- Toppings Station: Set up bowls of cheese, diced olives (for “monster eyes”), tiny pepper bits (“seed spiders”), or chopped herbs. Let them customize.
- Counting Carbs: Turn it into a learning moment—show them how these peppers are healthy and low in sugars.
Variations & Swaps
- Meat Swap: Turkey, chicken, or Italian sausage work great. Adjust spices for boldness.
- Vegetarian Option: Use crumbled tempeh or beef-style plant-based “meat.”
- Cheese-Free: Mix nutritional yeast or stir some mashed avocado or dairy-free pesto into the filling.
- Spicy: Add diced jalapeños or a pinch of paprika for a kick.
Make-Ahead + Freezer Hacks
Make Ahead:
- Assemble stuffed peppers and refrigerate (covered) up to 24 hours before baking.
- Bake them fresh the next day—easy weeknight dinner!
Freezer Meal Prep:
- Prep and stuff stuffed peppers, place in a freezer-safe container (cover tightly).
- Freeze up to 3 months.
- When ready, thaw overnight in fridge and bake as instructed (may take +5 minutes).
Reheating Tips
- Oven: 350°F (175°C) for 10–15 minutes, until heated through.
- Microwave: 1–2 minutes on medium, but cheese won’t crisp.
- Air Fryer (Bonus!): 5–7 minutes at 350°F—gets crispy edges and melty cheese.
