Let’s make it together with these easy steps:
Preheat your oven to 350°F (175°C) and gather your baking dish; a 9×13 casserole dish works wonderfully.
In a large skillet over medium heat, brown the ground beef with the diced onion and bell pepper until the meat is fully cooked and the veggies are tender. Drain any excess grease.
Stir in the low-carb pizza sauce and Italian seasoning, seasoning with salt and pepper to taste. Remove from heat and set aside.
Layer half of the meat mixture at the bottom of the prepared baking dish. Sprinkle one cup of shredded mozzarella cheese over it.
Add your choice of toppings generously—don’t hold back! Then layer the remaining meat mixture on top, followed by another cup of mozzarella cheese.
Bake in the preheated oven for 20-25 minutes, or until bubbly and golden on top. Allow it to cool for a few minutes before serving.
Variations & Creative Twists
Feel free to make this dish your own with these fun ideas:
- Veggie Delight: Substitute additional chopped vegetables like zucchini, mushrooms, or spinach to add texture and nutrients.
- Spicy Kick: Add jalapeños or crushed red pepper for a zesty twist that gives your casserole a bit of heat.
- Creamy Addition: Swirl in some cream cheese into the meat mixture for a rich, velvety layer that provides a comforting, indulgent experience.
- Bacon Lovers Unite: Top it off with crispy turkey bacon for that salty crunch that compliments the flavors beautifully.
Chef Emma’s Helpful Tips
- Meal Prep Pro: Make the casserole in advance—store the unbaked dish in the fridge for up to 24 hours or freeze for a future cozy meal.
- Ingredient Swaps: You can easily swap beef for turkey or even a meat alternative for a lighter, plant-based option.
- Leftover Magic: If you have leftovers, store them in an airtight container in the fridge for up to 3 days. Reheat in the oven for optimal cheesy goodness.
- Perfect Slices: For easy serving, allow the casserole to set for a few minutes after baking. This helps it hold its shape when slicing.
