Preheat your oven to the BROIL setting and position the oven rack in the center of the oven. Keeping the tray too close to the top heating element can cause the cheese to burn before the peppers soften properly. Allow the oven to fully preheat while you prepare the ingredients so the peppers cook evenly and quickly.

Wash the mini sweet peppers thoroughly under cool running water and pat them completely dry with paper towels. Slice each pepper in half lengthwise using a sharp knife, then carefully remove the seeds and white membranes from the inside. Try to keep the pepper halves intact because they act as little “nacho boats” that hold all the delicious toppings.

Arrange the pepper halves cut-side up on a large baking sheet or oven-safe tray. Leave a small amount of space between each pepper so the heat can circulate properly around them. Overcrowding the pan can cause the peppers to steam instead of roast, which may lead to softer, watery nachos.

Heat a large skillet over medium heat and add the ground beef. Use a spoon or spatula to break the meat into small crumbles as it cooks. Continue stirring occasionally so the beef browns evenly and develops rich flavor instead of clumping together.

Once the beef begins to brown, sprinkle in the cumin, chili powder, and salt. Stir thoroughly to coat all the meat evenly with the seasonings. Continue cooking for several more minutes until the beef is fully browned, fragrant, and slightly crispy in some spots for extra taco-style flavor.

If there is excess grease in the skillet, carefully drain it before assembling the peppers. Removing extra grease helps prevent the peppers from becoming oily while baking and keeps the nachos tasting balanced instead of heavy.

Using a spoon, carefully fill each mini pepper half with the seasoned taco meat. Gently press the meat down into the peppers so it stays in place during baking. Don’t worry if some filling spills slightly onto the tray — rustic-style nachos always look more natural and appetizing.

Sprinkle shredded cheddar cheese generously over each stuffed pepper half, making sure the meat is mostly covered. The cheese melts down beautifully during broiling and creates that classic gooey nacho texture everyone loves.

Add sliced jalapeños on top if you want extra spice and bold flavor. You can adjust the amount depending on your preferred heat level, or leave them off completely for a milder family-friendly version.

Place the baking tray into the oven and broil the peppers for approximately 5–6 minutes. Watch them closely because broilers can vary in strength and the cheese can brown quickly. The peppers are ready when the cheese becomes fully melted, bubbly, and lightly golden around the edges while the peppers soften slightly but still hold their shape.

Carefully remove the tray from the oven and allow the peppers to cool for about 1–2 minutes before adding fresh toppings. This short resting time helps the cheese settle slightly and makes the peppers easier to handle.

Finish the keto mini pepper nachos with diced avocado, chopped tomatoes, sour cream, fresh cilantro, or any favorite low-carb nacho toppings you enjoy. Serve them warm while the cheese is still melty and stretchy for the ultimate keto comfort food experience.
