Keto Ground Beef Casserole Ingredients
Whether you’re meal prepping or whipping up a last-minute dinner, having the right ingredients is key to hitting all the right notes in this comforting dish!
For the Beef Mixture
- Ground Beef – A rich protein source; opting for lean ground beef reduces fat while preserving flavor.
- Fennel Seed – Imparts a signature Italian sausage flavor; for a gentler taste, feel free to omit it.
- Italian Seasoning – Elevates the complexity of flavors; can be swapped with dried oregano or basil if needed.
- Paprika – Adds a lovely smokiness; choose smoked paprika for an even deeper flavor.
For the Vegetable Base
- Cauliflower Florets – A fantastic low-carb pasta substitute; riced cauliflower or broccoli also works wonderfully if you prefer.
For the Creamy Sauce
- Parmesan Cheese – Introduces a nutty depth to the sauce; nutritional yeast is a great dairy-free alternative.
- Cream Cheese – Ensures a creamy texture; substitute with ricotta or cottage cheese for different flavor notes.
- Heavy Cream – Provides a luscious richness; unsweetened almond milk or whole milk can lower the carbs without sacrificing creaminess.
- Egg – Acts as a binder to create a rich sauce; a flaxseed meal mixed with water serves as a vegan replacement.
For the Topping
- Marinara Sauce – Adds a zesty layer of flavor; opt for low-carb brands like Rao’s or Organico Bello to stay true to keto.
- Mozzarella Cheese – Melts beautifully for a gooey topping; feel free to substitute with any cheese that melts well.

How to Make Keto Ground Beef Casserole
-
Preheat the Oven: Start by preheating your oven to 400°F (200°C). This ensures your casserole bakes evenly and comes out perfectly golden brown.
-
Brown the Beef: In a skillet over medium heat, brown the ground beef along with fennel seeds, Italian seasoning, and paprika, cooking until fully browned and fragrant, about 5-7 minutes.
-
Prepare the Cauliflower: Microwave the cauliflower florets for about 5 minutes until tender. This softens them, making them a perfect low-carb base for your casserole.
-
Mix Ingredients: Combine the cooked cauliflower with the browned ground beef in a large mixing bowl, stirring well. Then transfer this hearty mixture into a greased baking dish.
-
Make the Creamy Sauce: In the same skillet, add cream cheese, heavy cream, and Parmesan cheese, stirring over low heat until everything melts into a smooth, creamy sauce.
-
Add the Egg: Allow the creamy mixture to cool slightly, then whisk in the beaten egg to help bind the sauce. Pour this over the beef and cauliflower mixture in the baking dish.
-
Top & Bake: Generously top your casserole with marinara sauce, then sprinkle the mozzarella cheese all over for that gooey, melty finish.
-
Bake Until Bubbly: Place the dish in the oven and bake for about 30 minutes, or until the cheese is golden and bubbly—your kitchen will smell heavenly!
Optional: For an extra flavor kick, garnish with fresh basil or parsley just before serving.

Keto Ground Beef Casserole Recipe FAQs
How do I choose the right ground beef for the casserole?
Absolutely! Look for lean ground beef (around 80% lean, 20% fat) to strike a balance between flavor and reduced grease. If you prefer a leaner option, ground turkey or chicken can also be delicious substitutes.
How should I store leftovers of the keto casserole?
Store leftover Keto Ground Beef Casserole in an airtight container in the fridge for up to 3 days. Simply reheat in the microwave or oven until it’s heated through and ready to enjoy again!
Can I freeze the casserole, and if so, how?
Very! To freeze, ensure the casserole is completely cooled, then transfer it to a freezer-safe container. Wrap it tightly and store for up to 3 months. To reheat, thaw the casserole overnight in the fridge and then bake at 350°F (175°C) for about 20 minutes, or until warmed through.
What if my casserole comes out too watery?
No worries! If the casserole is too watery, it’s likely from the moisture in the cooked cauliflower or marinara sauce. Try draining excess liquid before combining it with the beef. Alternatively, you can add a bit of almond flour or ground flaxseed to help thicken it up.
Can I use other vegetables instead of cauliflower?
Absolutely! Riced cauliflower is a fantastic low-carb option, but feel free to swap in steamed broccoli or zucchini for a delightful twist. Just ensure whatever veggie you choose is cooked until tender before mixing it with the beef for even flavor throughout.
