About This Recipe
Keto Ground Beef Spinach Alfredo Casserole combines two comfort-food classics — creamy alfredo sauce and savory ground beef — into one rich, satisfying low-carb bake. This dish is incredibly comforting, easy to assemble, and perfect for nights when you want something warm and filling without spending much time cooking. The base is browned ground beef seasoned with simple aromatics, layered with spinach for freshness and volume, and coated in a smooth, velvety alfredo sauce made from heavy cream, cream cheese, garlic, and mozzarella.
As the casserole bakes, the sauce thickens and melds with the beef, creating a rich and cohesive texture throughout. The spinach softens into the sauce, adding color and nutrients without overpowering the flavor. A final topping of melted mozzarella creates a bubbly, golden layer that ties everything together in true comfort-food fashion. The result is a creamy, savory, protein-packed meal that feels indulgent while staying fully keto.
This recipe is also ideal for meal prep. It reheats exceptionally well — the sauce stays creamy, and the flavors deepen overnight. You can customize the casserole with mushrooms, cauliflower, different cheeses, or spices depending on your preference. It’s also a budget-friendly way to create a filling keto dinner that yields multiple portions.
Whether you’re browsing your Keto Ground Beef Recipes board or planning easy low-carb meals for the week, this casserole is a dependable option. It’s simple, hearty, and delicious enough to satisfy both keto and non-keto eaters. With minimal prep and maximum flavor, it’s perfect for quick weeknights, feeding a family, or building out your meal prep rotation.
