Keto Beef Taco Stuffed Peppers — A High-Protein, Low-Carb Mexican Dinner the Whole Family Will Love
If you have been craving Mexican food on keto, Keto Beef Taco Stuffed Peppers are the answer.

On taco seasoning: Many store-bought taco seasonings contain cornstarch, sugar, or other fillers that add hidden carbs.

Step-by-Step Instructions
1. Preheat the oven and prep the peppers
Preheat your oven to 375 degrees Fahrenheit or 190 degrees Celsius. Cut each bell pepper in half lengthwise from top to bottom, keeping the stem intact on one half if you like for presentation. Remove the seeds and white membranes from inside each pepper half. Brush the inside and outside of each pepper half lightly with olive oil and season with a pinch of salt and pepper. Arrange the pepper halves cut-side up in a large baking dish.
2. Pre-roast the peppers
Place the baking dish in the preheated oven and roast the empty pepper halves for about 10 to 12 minutes. This pre-roasting step softens the peppers slightly so they are fully tender by the time the filling is cooked and the cheese is melted. Skip this step if you prefer firmer, crunchier peppers. Remove from the oven and set aside while you make the filling.
3. Cook the taco beef filling
Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it up with a spatula, until browned and no longer pink, about 7 to 8 minutes. Drain any excess fat if needed, leaving just a small amount for flavor.
Add the diced onion to the skillet and cook for 2 to 3 minutes until softened and translucent. Add the minced garlic and cook for another minute until fragrant. Stir in the taco seasoning, smoked paprika, and cumin, making sure the spices coat the meat evenly. Pour in the beef broth or water and stir to combine, allowing the liquid to cook down and the seasoning to fully absorb into the meat, about 2 minutes. Stir in the salsa or diced tomatoes with green chiles and cook for another 1 to 2 minutes. Taste the filling and adjust seasoning as needed.
4. Fill the peppers
Spoon the taco beef filling generously into each pre-roasted pepper half, pressing down slightly to pack the filling in and mounding it slightly above the rim of each pepper. Every pepper should be well filled — do not be shy with the meat.
5. Top with cheese and bake
Sprinkle the shredded cheese generously over each filled pepper, covering the meat completely. Place the baking dish back in the oven and bake for 15 to 20 minutes, or until the cheese is fully melted, bubbly, and starting to turn golden brown in spots and the peppers are fully tender.
6. Garnish and serve
Remove from the oven and let the stuffed peppers rest for 3 to 5 minutes. Top each pepper with a dollop of sour cream, slices of fresh avocado, chopped cilantro, and jalapeño slices if desired. Serve with lime wedges on the side for squeezing over the top.
Serving Ideas and Pairings
Keto Beef Taco Stuffed Peppers are a complete meal on their own, but you can round out the dinner with simple low-carb sides.
For strict keto: Serve with a simple shredded cabbage slaw dressed with lime and olive oil, or a side of guacamole and sliced cucumber for scooping.
For a bigger spread: Add a simple Mexican cauliflower rice cooked with cumin, garlic, and lime as a side dish to soak up any extra taco juices.
For entertaining: Arrange the stuffed peppers on a large platter with all the toppings in small bowls on the side so guests can customize their own.
Flavor Variations
Ground turkey taco peppers — Swap ground beef for lean ground turkey for a lighter version with similar macros.
Chicken taco peppers — Use shredded rotisserie chicken tossed in taco seasoning and salsa for a faster, no-cook filling option.
Spicy chorizo peppers — Replace half the ground beef with Mexican chorizo for a richer, spicier filling.
Cheesy double-stuffed — Mix cream cheese into the taco filling before stuffing for an ultra-creamy, cheesy center.
All of these variations can become future pins using the same stuffed pepper base technique.
How to Fit This Into a Keto Plan
- Net carbs: About 7 to 9 grams per stuffed pepper half, primarily from the bell pepper and salsa
- Protein: Around 28 to 35 grams per serving from ground beef and cheese
- Fat: Moderate to high from beef, cheese, sour cream, and avocado — easily adjusted based on toppings
For strict keto, choose green bell peppers which are slightly lower in carbs than red or yellow, and use a zero-carb taco seasoning blend.
Meal Prep and Storage
Fridge: Store cooked stuffed peppers in airtight containers for up to 4 days. Reheat in the microwave for 2 to 3 minutes or in the oven at 350 degrees Fahrenheit until heated through.
Freezer: Freeze stuffed peppers without fresh toppings for up to 2 months. Wrap individually in foil, then transfer to a freezer bag. Thaw overnight in the fridge and reheat in the oven.
Make ahead: Prepare the taco filling up to 2 days in advance and store in the fridge. When ready to serve, fill the peppers, top with cheese, and bake.
Tips for Perfect Keto Taco Stuffed Peppers Every Time
- Pre-roast the peppers for best texture — raw peppers can end up underdone if you skip this step.
- Drain excess fat from the beef to prevent the filling from being greasy and watery.
- Pack the filling generously — overfilled peppers look better in photos and are more satisfying to eat.
- Use freshly shredded cheese — it melts more smoothly than pre-shredded bags which contain anti-caking agents.
- Rest before serving — letting them sit for a few minutes after baking makes them easier to plate and eat.
