Ingredients
Method
- Prep the aromatics. Finely mince half the onion and half the green pepper for the meatballs. Slice the remaining onion and pepper into thin strips for sautéing later. If using mushrooms, slice them now.
- Make the meatball mix. In a large bowl, combine ground beef, minced onion and pepper, egg, almond flour, Worcestershire sauce, garlic, 1 teaspoon salt, and 1/2 teaspoon black pepper. Mix gently with your hands until just combined. Don’t overmix or the meatballs can turn dense.
- Form the meatballs. Roll into golf ball–sized portions (about 1.5 inches). You should get 18–22 meatballs. Place them on a plate or sheet pan.
- Sauté the veggies. Heat 1 tablespoon oil in a large skillet over medium heat. Add sliced onion and peppers (and mushrooms, if using). Season with a pinch of salt and cook 6–8 minutes until softened and lightly browned. Transfer to a plate and keep warm.
- Brown the meatballs. In the same skillet, add the remaining oil. Add meatballs in a single layer without crowding. Brown on all sides, about 6–8 minutes total. Work in batches if needed. They don’t need to be fully cooked yet.
- Finish in the oven (recommended). Transfer browned meatballs to a parchment-lined sheet pan and bake at 375°F (190°C) for 8–10 minutes, or until they reach an internal temperature of 160°F (71°C). If you prefer, you can simmer them covered on low for 8–10 minutes, but baking keeps them crisp.
- Make the cheese sauce. While the meatballs finish, return the skillet to medium-low heat. Add heavy cream and cream cheese, whisking until smooth and slightly thickened, 3–4 minutes. Stir in shredded or torn provolone/mozzarella until melted. If the sauce is too thick, whisk in beef broth, a splash at a time. Season with salt, pepper, and a pinch of red pepper flakes if you like heat.
- Combine and melt. Add the meatballs back to the skillet, spoon the sautéed peppers and onions over the top, and gently coat with the cheese sauce. If using sliced provolone, lay slices over the meatballs and cover the pan for 1–2 minutes to melt.
- Serve. Spoon meatballs and sauce into bowls or onto plates. Garnish with chopped parsley if you want a fresh touch. They’re great on their own, over cauliflower rice, or with a side salad.

- Freezer: Freeze meatballs without the cheese sauce for up to 3 months. Thaw overnight in the fridge, then reheat and make fresh sauce.
- Reheating: Warm gently on the stove over low heat, stirring in a splash of beef broth or cream to loosen the sauce.
Microwave in short bursts, covered, to prevent drying.
Why This is Good for You
These meatballs offer solid protein from beef to keep you satisfied. The cheese and cream add fat for steady energy on a keto plan, while staying low in carbs. Peppers, onions, and mushrooms bring fiber, antioxidants, and flavor without pushing up net carbs too much.
You’ll feel like you’re eating comfort food while staying aligned with your goals. It’s a smart swap for the bread-heavy original.
Common Mistakes to Avoid
- Overmixing the meat. This can make meatballs tough. Mix until ingredients just come together.
- Skipping the binder. Almond flour helps keep the meatballs tender and hold their shape.
Don’t leave it out unless substituting with crushed pork rinds.
- Overcooking. Dry meatballs are a letdown. Use a thermometer and pull at 160°F.
- Boiling the cheese sauce. High heat can split dairy. Keep it at a gentle simmer and whisk often.
- Crowding the pan. Meatballs won’t brown well if crammed together.
Brown in batches for best flavor.
Recipe Variations
- Mild & melty: Use mozzarella for a stretchier, milder sauce.
- Sharp & bold: Swap in half provolone and half white cheddar for more bite.
- Mushroom lover’s: Double the mushrooms and add a splash of Worcestershire to the sauce.
- Spicy kick: Add diced jalapeño to the meat mixture and a pinch of cayenne to the sauce.
- Pork-beef blend: Use half ground pork for extra juiciness.
- No-dairy option: Use a dairy-free cream and a keto-friendly melting cheese alternative. Flavor with nutritional yeast for cheesiness.
- Air fryer method: Brown meatballs at 390°F (200°C) for 8–10 minutes, shaking once, then finish with sauce on the stovetop.
FAQ
Can I use ground turkey instead of beef?
Yes, but choose 85–93% lean for moisture. Turkey is leaner, so don’t skip the binder, and consider adding 1 tablespoon olive oil to the mixture.
Cook to 165°F for safety.
What’s the best cheese for a classic cheesesteak flavor?
Provolone gives the most authentic taste and melts smoothly. You can blend in mozzarella for extra stretch or a little white American cheese for creaminess.
How do I keep the sauce from getting grainy?
Use low heat, whisk continuously, and add cheese gradually. If it thickens too much, whisk in warm beef broth or a splash of cream to smooth it out.
Are onions and peppers too high in carbs for keto?
In moderate amounts, they fit well.
The recipe uses reasonable portions spread over multiple servings, keeping net carbs in check while adding flavor and texture.
Can I make these ahead for meal prep?
Absolutely. Cook the meatballs and sauté the veggies in advance. Store separately, then reheat and make the cheese sauce fresh for best texture.
What can I serve with these to keep it keto?
Try cauliflower rice, zucchini noodles, roasted broccoli, or a crisp side salad with olive oil and vinegar.
How many meatballs is a serving?
For most appetites, plan on 3–4 meatballs per person with sauce and veggies.
Adjust based on your macros and side dishes.
Can I skip the almond flour?
You can replace it with 1/3 cup finely crushed pork rinds for zero net carbs and great texture. Without any binder, the meatballs may be denser and more prone to breaking.
