- Diet compatibility: Low-carb, keto-friendly, sugar-free options
Ingredients
- 1 lb ground beef (85% lean)
- 1 small onion, diced
- 3 cloves garlic, minced
- 1 cup beef broth
- 1 cup marinara sauce (no sugar added preferred)
- 1 cup shredded mozzarella cheese
- 1/2 cup sour cream
- 1 cup shredded cheddar cheese
- 1/2 tsp dried oregano
- 1/2 tsp dried Italian seasoning
- Salt and pepper, to taste
- Optional add-ins: 1 cup chopped mushrooms, 1 cup spinach, or 1 small zucchini, diced
- Optional topping: 1/4 cup grated parmesan
Ingredient Notes
- Ground beef: Choose 85% lean for flavor without excess grease. If you use a leaner option, you may want to add a teaspoon of olive oil.
- Marinara: Use a sauce with no added sugar to keep this dish keto-friendly; you can also use crushed tomatoes with a pinch of garlic and oregano.
- Cheese: Freshly shredded mozzarella and cheddar melt beautifully and give that gooey, golden top. Do not pre-mix all cheese; reserve a portion for the final layering to maximize melty results.
- Flavor boosters: A pinch of red pepper flakes can wake up the dish if you like a little heat.
- Vegetables: Mushrooms and spinach add umami and color; cook them with the beef so they release moisture and flavors mingle.
Step-by-Step Instructions
- Preheat and prep: Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch casserole dish.
- Brown the beef: In a large skillet, sauté the onion in a splash of oil until translucent. Add garlic and, if using, mushrooms; cook until they’re golden. Add ground beef; cook until browned, breaking it apart as it cooks. Season with salt, pepper, oregano, and Italian seasoning.
- Create the sauce: Pour in the beef broth and marinara. Stir to combine and simmer for 5 minutes, allowing the flavors to meld. If you’re adding greens like spinach, fold them in now until just wilted.
- Creamy layer: Remove from heat and stir in sour cream until the mixture is creamy and smooth.
- Layer and top: Transfer the beef mixture to the baking dish. Sprinkle with half of the mozzarella, then add a light layer of cheddar. Top with the remaining mozzarella and cheddar (or reserve a small handful to sprinkle on top for the final golden crust).
- Bake to bubbly: Bake in the preheated oven for 20–25 minutes, until the cheese is melted, bubbling, and the top is golden brown. For extra crusty edges, broil for 1–2 minutes, watching closely.
- Rest and serve: Let the casserole rest for 5 minutes before slicing. This helps set the layers and makes serving easier.
Pro Tips / Variations
- Flavor twists: Add a pinch of smoked paprika or cumin for a deeper, smoky flavor. Mix in chopped fresh parsley after baking for a fresh finish.
- Veggie swaps: Swap in finely chopped zucchini or bell peppers for extra texture and color without changing the composition much.
- Cheese ideas: Use pepper jack for a mild kick, or top with a mix of feta and mozzarella for a tangy finish.
- Make ahead: Assemble (without baking) and refrigerate up to 24 hours. Bake at 375°F for 30–35 minutes.
- Storage: Store leftovers in an airtight container for up to 3 days in the fridge. Freeze individual portions for longer-term storage.
