Keto Ground Beef & Spinach Skillet - Easy, Flavorful, and Ready in 20 Minutes
Ingredients
Method
- Heat the skillet: Place a large skillet over medium-high heat. Add 1 tablespoon oil and let it shimmer.
- Brown the beef: Add the ground beef, breaking it up with a spatula. Season with salt and pepper. Cook until browned with crisp edges, 5–7 minutes. Transfer beef to a bowl and drain excess fat if needed, leaving about 1 tablespoon in the pan.
- Sauté aromatics: Add the remaining oil if the pan looks dry. Stir in the onion and cook until translucent, about 3 minutes. Add the garlic and cook 30 seconds, stirring so it doesn’t burn.
- Season it up: Sprinkle in Italian seasoning, smoked paprika, and red pepper flakes if using. Toast the spices for 20–30 seconds to wake up the flavors.
- Wilt the spinach: Add the spinach in batches, tossing until it wilts down. This takes 1–2 minutes. Don’t worry if the pan looks full—the spinach shrinks quickly.
- Bring it together: Return the beef to the skillet. Pour in the heavy cream and stir. Let it simmer on medium-low for 2–3 minutes until slightly thickened.
- Add the cheese: Stir in mozzarella until it melts and coats the beef and spinach. Finish with Parmesan for extra depth. Taste and adjust salt and pepper.
- Finish and serve: Squeeze a little lemon over the skillet to brighten the flavors. Garnish with parsley or chives. Serve hot as is or with cauliflower rice or zucchini noodles.

How to Store
- Refrigerate: Cool completely, then transfer to an airtight container.
Store up to 4 days.
- Freeze: Portion into freezer-safe containers and freeze up to 3 months. Thaw in the fridge overnight.

Health Benefits
- Ketosis-friendly macros: Ground beef and cheese provide protein and fat, helping you feel full while keeping carbs low.
- Nutrient-dense greens: Spinach offers vitamin K, folate, vitamin A, and magnesium in a very low-carb package.
- Stable energy: Balanced fat and protein can support steady energy and fewer cravings between meals.
- Electrolyte support: Spinach’s potassium and magnesium help support electrolyte balance, which is important on keto.
Pitfalls to Watch Out For
- Hidden carbs in add-ins: Some store-bought spice blends, sauces, or pre-shredded cheeses may contain fillers.
Check labels for added starch or sugar.
- Too much liquid: Spinach releases water. If the skillet looks watery after wilting, simmer a minute longer before adding cheese, or drain lightly.
- Overcooking the spinach: It should be just wilted and bright green. Overcooked spinach turns dull and mushy.
- Grease overload: If using higher-fat beef, drain excess fat so the final dish isn’t greasy.
Leave a tablespoon for flavor.
- Heavy hand with salt: Cheese and Parmesan are salty. Season in layers and taste before adding more.
Alternatives
- Protein swaps: Ground turkey, chicken, or pork all work. Add 1 tablespoon butter or extra oil if using very lean meat.
- Dairy-free: Use full-fat coconut milk instead of cream and a dairy-free melting cheese alternative.
Add nutritional yeast for a savory boost.
- Veggie additions: Mushrooms, zucchini, bell peppers, or riced cauliflower cook quickly and add volume without many carbs.
- Spice variations: Try cumin and chili powder for a Tex-Mex feel, or curry powder and a pinch of ginger for a warming twist.
- Cheese choices: Swap mozzarella for Monterey Jack, cheddar, or fontina. Keep the Parmesan for that salty finish.
FAQ
Can I make this ahead for meal prep?
Yes. Cook as directed, cool completely, and refrigerate in portions.
It reheats well and keeps its texture for several days.
Is frozen spinach okay to use?
It works, but thaw and squeeze out excess water first. Use about 10 ounces of frozen spinach in place of fresh to keep the texture saucy, not watery.
What can I serve this with on keto?
Great options include cauliflower rice, sautéed zucchini noodles, roasted asparagus, or a simple side salad with olive oil and lemon.
How do I make it spicier?
Add extra red pepper flakes, a diced jalapeño with the onions, or a dash of hot sauce at the end.
Can I use half-and-half instead of heavy cream?

Leaner beef can work, but add a little extra oil and watch the cooking time to avoid dryness.
