Recipe Information

Ingredients

• 1 1/2 pounds lean ground beef (90% lean), halal-certified
• 1 tablespoon olive oil
• 1 medium yellow onion, finely diced
• 2 medium zucchini (about 14 ounces / 400g), quartered lengthwise and sliced
• 1 medium red bell pepper, diced
• 3 garlic cloves, minced
• 1 tablespoon tomato paste
• 1 teaspoon smoked paprika
• 1 teaspoon ground cumin
• 1/2 teaspoon dried oregano
• 3/4 teaspoon fine salt, plus more only if needed
• 1/2 teaspoon black pepper
• 1/4 teaspoon red pepper flakes, optional
• 1 cup shredded cheddar cheese (about 4 ounces / 115g)
• 2 tablespoons chopped fresh parsley, for serving

Step-by-Step Instructions

1. Prepare the vegetables

Dice the onion and pepper, slice the zucchini, and mince the garlic before heating the skillet. Bite-size zucchini half-moons cook quickly but still hold their shape.

2. Brown the beef

Heat a large 12-inch skillet over medium-high heat. Add the olive oil and ground beef, press the meat into an even layer, and leave it alone for about 2 minutes so browned edges can develop. Break it into small crumbles and cook for 5 to 6 minutes, until no pink remains. If the beef releases a lot of fat, carefully spoon off all but about 1 tablespoon.

3. Cook the vegetables and seasonings

Add the onion and cook for 2 minutes, stirring occasionally. Add the zucchini and bell pepper and cook for 4 to 5 minutes, until just tender with a little bite left. Stir in the garlic, tomato paste, smoked paprika, cumin, oregano, salt, black pepper, and red pepper flakes. Cook for 1 minute, stirring so the tomato paste darkens slightly and coats the beef.

4. Finish with cheese

Reduce the heat to low. Scatter the cheddar over the skillet, cover, and cook for 2 to 3 minutes, just until melted. Sprinkle with parsley and serve right away. Check the center of the beef with an instant-read thermometer; ground beef must reach 71°C / 160°F.

Tips for Best Results

Choose a wide, heavy skillet instead of a crowded saucepan. The extra surface area lets moisture cook off, helping the beef brown and keeping the finished skillet from turning watery.

Salt the zucchini only when it goes into the pan. Salting it ahead draws out water and can make the vegetables steam. Cook it until tender-crisp; if liquid gathers in the skillet, leave it uncovered for another minute before adding the cheese.

Block cheddar generally melts more smoothly than pre-shredded cheese, which can contain anti-caking starches. Keep the heat low once the cheese goes in so it melts without becoming oily.

Ingredient Substitutions

Ground lamb makes a richer substitute for the beef; drain a little more fat after browning. Ground turkey works too, but add an extra teaspoon of olive oil and a pinch more salt because it is leaner.

Swap the zucchini for chopped mushrooms, cauliflower florets, or green beans. Use Monterey Jack, mozzarella, or a mild cheddar blend in place of cheddar. For a dairy-free version, omit the cheese and finish with sliced avocado and extra parsley.

What to Serve With

The skillet is filling on its own, but it also works with a crisp cucumber salad, cauliflower rice, or roasted broccoli. For another easy ground-beef meal, try Easy Ground Beef Skillet Dinner.

Storage Instructions

Cool leftovers promptly and refrigerate them in an airtight container for up to 4 days. For longer storage, freeze individual portions for up to 2 months. The zucchini will soften a little after freezing, but the flavor still holds up.

Reheating Instructions

Reheat a serving in a covered skillet over medium-low heat with 1 tablespoon of water for 4 to 6 minutes, stirring once or twice, until hot throughout. A microwave works too: cover loosely and heat in 60-second bursts, stirring between each burst. Reheat leftovers to 74°C / 165°F before eating.

Frequently Asked Questions

Is beef mince suitable for a keto diet?

Plain beef mince has no meaningful carbohydrates. In this recipe, the carbohydrates come mainly from the onion, zucchini, pepper, and small amount of tomato paste, so the finished serving remains low in carbs.

Can I make this recipe ahead?

Yes. Cook the skillet through the vegetable step, cool it, and refrigerate for up to 2 days. Reheat gently, then add the cheese just before serving for the best texture.

How do I keep ground beef from turning gray?

Use medium-high heat, avoid overcrowding the pan, and let the beef sit briefly before stirring. Browning needs room for moisture to evaporate, so cook in two batches if your skillet is small.

Are the nutrition values exact?

They are per-serving estimates based on the listed ingredients and four servings. Brand, beef leanness, and how much rendered fat is drained can change the final values.

Can I use frozen zucchini?

Fresh zucchini is best because it stays firmer and releases less water. If you are using frozen zucchini, thaw it completely and press it dry in a clean kitchen towel first. Add it for the final 2 to 3 minutes of vegetable cooking rather than at the beginning. The skillet will be softer, but this limits excess water and lets the cheese melt into a richer sauce.

Conclusion

This keto beef mince recipe is a practical low-carb dinner built from everyday ingredients. Brown the beef well, cook the vegetables only until tender, then melt the cheddar at the end. Change the vegetables or cheese when you want variety without changing the basic skillet method.
