Keto Ground Beef and Pepper Skillet (Fast Weeknight Dinner) - One-Pan, Low-Carb Comfort
Ingredients
- Ground beef: 1 to 1.25 pounds (80/20 or 85/15 works best)
- Bell peppers: 3 medium (mix of red, yellow, green for color)
- Onion: 1 small yellow or white onion
- Garlic: 3 cloves
- Tomato paste: 2 tablespoons (adds richness without many carbs)
- Beef broth: 1/2 cup (low-sodium preferred)
- Cheese: 1 to 1.5 cups shredded (cheddar, Monterey Jack, or pepper jack)
- Olive oil or avocado oil: 1 tablespoon (if your beef is very lean)
- Spices: Chili powder, smoked paprika, ground cumin, dried oregano
- Salt and black pepper
- Optional add-ins: Red pepper flakes, a splash of hot sauce, lime juice, fresh cilantro
Instructions
- Prep your produce: Slice the bell peppers into thin strips. Dice the onion and mince the garlic. Grate the cheese if not pre-shredded.
- Brown the beef: Heat a large skillet over medium-high. Add ground beef (and oil if using). Break it up with a spatula and cook until browned, about 5–6 minutes.
- Season the meat: Stir in 1.5 teaspoons salt, 1 teaspoon black pepper, 1.5 teaspoons chili powder, 1 teaspoon smoked paprika, 1 teaspoon cumin, and 1/2 teaspoon dried oregano. Cook 1 minute until fragrant.
- Sweat the aromatics: Add the diced onion. Cook 3 minutes until it softens. Add garlic and sauté 30 seconds.
- Add the peppers: Toss in the sliced bell peppers. Cook 4–6 minutes, stirring occasionally, until they’re tender-crisp. Don’t overcook—you want a little snap.
- Make it saucy: Stir in the tomato paste. Cook 1 minute to caramelize slightly. Pour in the beef broth and scrape up any browned bits from the pan. Simmer 2–3 minutes to thicken.
- Finish and melt: Taste and adjust seasoning. If you like heat, add red pepper flakes or hot sauce. Sprinkle the cheese over the skillet, reduce heat to low, cover, and let it melt for 1–2 minutes.
- Brighten it up: Optional but great—squeeze a little lime juice over the top and garnish with chopped cilantro.
- Serve: Spoon into bowls as is, or serve over cauliflower rice or in lettuce cups for a handheld option.

Health Benefits
- Keto-friendly macros: Ground beef provides protein and fats to help keep you satisfied and support ketosis.
- Low-carb veggies: Bell peppers add fiber, vitamin C, and antioxidants with relatively few carbs per serving.
- Balanced satiety: The combination of protein, fat, and fiber helps curb cravings and keep energy stable.
- Gluten-free and grain-free: Naturally fits many dietary needs without substitutions.
Common Mistakes to Avoid
- Overcrowding the pan: If your skillet is small, brown the beef in batches so it sears instead of steaming.
- Overcooking the peppers: They should be tender with some bite.
Mushy peppers can make the dish feel heavy.
- Skipping the tomato paste step: Briefly cooking it builds deeper flavor and reduces any raw taste.
- Not seasoning enough: Taste as you go. Salt enhances the natural sweetness of the peppers and the savoriness of the beef.
- Using too lean beef without added fat: Add a bit of oil or butter if using 90% lean or higher to prevent dryness.
Variations You Can Try
- Southwest-style: Add a pinch of coriander and finish with avocado slices and a dollop of sour cream.
- Italian flair: Swap chili powder for Italian seasoning, use mozzarella or provolone, and finish with basil.
- Philly-inspired: Use green peppers only, add sliced mushrooms, and top with provolone.
- Spicy chipotle: Stir in 1–2 teaspoons minced chipotle in adobo and use pepper jack cheese.
- Turkey or chicken: Substitute ground turkey or chicken and add 1 tablespoon olive oil for moisture.
- Extra veg: Toss in zucchini half-moons or spinach in the last 2 minutes of cooking.
FAQ
Is this recipe strictly keto?
Yes, it’s designed to be low in carbs and high in fat and protein. Bell peppers do contain some carbs, but the amount per serving stays within typical keto guidelines when portioned reasonably.
Can I make it dairy-free?
Absolutely.
Skip the cheese or use a dairy-free, low-carb cheese alternative. You can also finish with extra olive oil or a dollop of dairy-free pesto for richness.
What can I serve it with to keep it keto?
Cauliflower rice, sautéed cabbage, roasted broccoli, or lettuce wraps all work well. If you want something creamy, try a side of mashed cauliflower.
How spicy is it?
As written, it’s mild.
For heat, add red pepper flakes, hot sauce, or diced jalapeño with the peppers. For no heat, skip the chili powder and use more smoked paprika and oregano.
Can I use frozen peppers and onions?
Yes. Sauté them straight from frozen over medium-high heat to evaporate moisture, then proceed as directed.
They may cook faster, so keep an eye on texture.
What’s the best cheese to use?
Cheddar melts well and adds sharpness. Monterey Jack is creamy and mild, and pepper jack brings a little kick. Use what you like or a blend.
How do I make it lower in fat?
Use 93% lean beef or ground turkey and drain any excess fat after browning.
You can also reduce the cheese or skip it entirely and add extra veggies.
