Yellow onion – Finely chopped to add sweetness and depth to the beef.
Garlic cloves – Minced for a punch of warm, aromatic flavor.
Olive oil – A tablespoon to sauté your aromatics and keep things moist.

For the Creamy Sauce

Cream cheese – Softened, it gives the casserole its creamy, comforting texture without added carbs.
Heavy cream – Adds richness and helps bind the casserole together perfectly.
Shredded cheddar cheese – Sharp and melty, this cheese adds that irresistible golden top.

How to Make Keto Ground Beef Casserole

Preheat Oven: Preheat your oven to 375°F while you gather and prep all ingredients. This ensures even heat distribution and guarantees that the casserole bakes to a perfect, bubbly, golden cheese topping.
Sauté Aromatics: Heat olive oil in a skillet over medium heat, then sauté chopped onion until translucent (about 3 minutes). Next, stir in minced garlic for another 30 seconds until wonderfully fragrant and golden.
Brown Beef: Add ground beef, breaking it up; cook 8–10 minutes until no pink remains, then drain excess fat for a leaner casserole.
Prepare Sauce: In a bowl, whisk softened cream cheese with heavy cream, dried Italian herbs, salt, and pepper until smooth and creamy.
Combine: Pour the cream sauce into the skillet with beef, stirring until every beef bit is coated in a rich, velvety mixture.
Assemble Casserole: Spoon the beef-sauce mixture into a greased 9×13″ casserole dish, then smooth the top with a spatula to ensure even layering and uniform browning in every bite.
Add Cheese: Generously sprinkle shredded cheddar and Parmesan over the top, distributing evenly so the casserole bakes into a bubbly, golden, and irresistible cheesy crust that seals in flavor.
Bake to Perfection: Bake in the preheated oven for 20–25 minutes until the cheese is bubbly and golden brown; then let the casserole rest 5 minutes to set beautifully before slicing.
Garnish & Serve: Garnish with freshly chopped parsley for a bright pop of color, then serve slices warm, savoring every comforting, keto-friendly bite alongside your favorite low-carb side.

Optional: Serve with roasted broccoli for extra low-carb crunch.

Keto Ground Beef Casserole Recipe FAQs

What type of ground beef is best for Keto Ground Beef Casserole?
I recommend using 85% lean ground beef. It strikes the perfect balance between juicy flavor and manageable fat content, preventing the casserole from becoming greasy but still keeping it delightfully moist.

How long can I store leftover Keto Ground Beef Casserole in the fridge?
Store your leftovers in an airtight container and enjoy them within 3 to 4 days. This timeframe ensures freshness, flavor, and safety. When reheating, use a gentle oven or microwave heat to keep the texture just right.

Can I freeze Keto Ground Beef Casserole? If so, how?
Absolutely! Freeze in a tightly sealed, freezer-safe container or wrap the dish well with plastic wrap and foil to prevent freezer burn. Label with the date and keep it frozen for up to 3 months. When ready to enjoy, thaw overnight in the fridge, then reheat in a 350°F oven for 15–20 minutes until warmed through.

What should I do if my casserole turns out watery or separates?
This usually happens if excess fat isn’t drained from the cooked ground beef or the cream cheese wasn’t softened properly. To fix it: drain all fat carefully after browning the beef and whisk the cream cheese thoroughly with heavy cream before mixing. Also, avoid overbaking which can release too much moisture.

Is Keto Ground Beef Casserole safe for pets or people with dairy allergies?
This casserole contains multiple dairy ingredients like cream cheese and cheddar, so it’s best not to share with pets or those with lactose intolerance or dairy allergies. For dairy-free alternatives, consider swapping cream cheese with dairy-free cream cheeses and use nutritional yeast instead of cheese, though it will slightly change the flavor.
