Key Ingredients That Make It Work

This casserole relies on a short list of pantry staples and one star player: ground beef. I use 85% lean because it has enough fat to keep things juicy, but you can go leaner if you preferjust don’t skip draining the excess fat after browning.

The cream cheese is what makes this dish feel indulgent. It melts into the beef and creates a creamy base that holds everything together. Cheddar adds sharpness and that irresistible melty top layer. The seasoningsgarlic powder, onion powder, cayenne, salt, and pepperbuild flavor without requiring a trip to the store.

Pro Tip: Cube the cream cheese before adding it to the skillet. It melts faster and blends more evenly that way.

Ingredient	Purpose	Easy Swap
Ground beef	Protein base, hearty texture	Ground turkey or pork
Cream cheese	Creamy binder	Sour cream or Greek yogurt
Cheddar	Melty, sharp topping	Monterey Jack or mozzarella
Cayenne pepper	Gentle heat	Omit or use paprika

How to Make It Step-by-Step

Start by preheating your oven to 400°F and lightly spraying a 2-quart casserole dish with olive oil. Heat a large nonstick skillet over medium-high, spray it lightly, and add the ground beef. Break it up as it cooks, stirring occasionally, until it’s no longer rawabout 5 minutes. Drain the fat and return the beef to the skillet.

Lower the heat to medium and stir in the salt, black pepper, garlic powder, onion powder, and cayenne. Add the cubed cream cheese and mix patiently until it’s fully melted and smooth. Turn off the heat and fold in half the shredded cheddar.

Transfer the beef mixture to your prepared casserole dish and sprinkle the remaining cheddar on top. Bake for about 10 minutes, just until the cheese is melted and bubbly. Garnish with chopped parsley and serve warm.

Note: It’s fine if the beef is still slightly pink after browningit finishes cooking in the oven. Leaving it a bit underdone at this stage keeps it juicy.

Smart Swaps and Simple Add-Ins

This keto ground beef casserole is endlessly adaptable. If you want to sneak in more veggies, toss in 1–2 cups of bell pepper strips, small broccoli or cauliflower florets, or chopped celery when you’re browning the beef. They’ll soften as they cook and blend right into the creamy base.

For a little extra kick, stir in a tablespoon of hot sauce like Sriracha before baking. If you love smoky flavors, add a half teaspoon of smoked paprika or chili powder along with the other seasonings. You can also skip the onion powder and sauté a medium chopped onion with the beef instead.

Shortcut: Use pre-shredded cheese and pre-minced garlic to save time. This dish is all about making weeknight cooking easier.

Storage, Reheating, and Meal Prep Tips

Store leftovers in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave, covered, at 50% power to keep the texture creamy. You can also freeze single servings for up to three monthsjust thaw overnight in the fridge before reheating.

If you’re meal prepping, divide the cooked casserole into portioned containers right after it cools. Label them with the date so you know what’s freshest. This dish holds up well in the freezer and tastes just as good after reheating as it does fresh.

Storage Method	Duration	Best Reheating Method
Refrigerator	Up to 4 days	Microwave, covered, 50% power
Freezer	Up to 3 months	Thaw overnight, then microwave

Pro Tip: If the casserole looks a little dry after reheating, stir in a spoonful of sour cream or a splash of heavy cream to bring back the creaminess.

Expert Says

Ground beef is an ideal protein base for keto ground beef casserole because its natural fat content helps you meet ketogenic macros while keeping you satisfied. The key is choosing 80/20 ground beef rather than lean versionsthat extra fat carries flavor and prevents the dish from drying out during baking while supporting ketosis.
