Ingredients for Deep Dish Pizza
- 1 lb lean ground beef (96/4 or leaner)
- 1 (15 oz) can diced tomatoes, drained
- 0.6 oz packet Italian seasoning mix (dry)
- Cooking spray
- 1 (10 oz) can refrigerated pizza dough (or homemade dough)
- 6 oz shredded part-skim mozzarella cheese
- 10–20 slices pepperoni (adjust to taste)
- Parsley flakes or chopped fresh parsley for garnish
Other topping ideas: Canadian bacon, pineapple, jalapeños, olives, mushrooms, spinach, or even diced fruit such as apples or pears for a unique twist.
Substitution Tips
If you prefer a lighter protein, substitute ground turkey or ground chicken for the beef. For a vegetarian version, omit the meat and bulk up the casserole with mushrooms, diced bell peppers, spinach, or zucchini. For a creamier texture, add small dollops of ricotta or cottage cheese between layers. If you need a low-carb option, use a low-carb crust alternative such as a Fat Head dough or a cauliflower-based crust.
How to Make Deep Dish Pizza Casserole
Step 1: Preheat the oven to 425°.
Step 2: In a nonstick skillet over medium-high heat, cook the ground beef until browned, breaking it apart as it cooks. Drain any excess fat if necessary, then return the beef to the skillet. Stir in the drained diced tomatoes and the Italian seasoning, and cook until the mixture is heated through.
Step 3: While the meat cooks, coat a 13 x 9-inch baking dish with cooking spray. Unroll the pizza dough and press it into the bottom of the dish, extending the dough up about halfway along the sides to form a shallow crust. Spread the meat and tomato mixture evenly over the dough.
Step 4: Bake the casserole, uncovered, at 425° for 12 minutes. Remove from the oven, sprinkle the shredded mozzarella over the top, arrange the pepperoni slices, and return to the oven for another 5 minutes or until the crust is golden and the cheese is melted and bubbling. Let the casserole rest for about 5 minutes before slicing.
Serve slices with a simple mixed-field-green salad and a light vinaigrette to balance the richness. Cut the casserole into 8 equal pieces; one piece is a serving.
Pro Tips
- Avoid packing the dough too tightly into the pan; leave a little room so it cooks through and crisps along the edges.
- Use a glass or ceramic baking dish for more even heat distribution and a nicely browned crust.
- If the top browns too quickly, tent the casserole loosely with foil for the last few minutes of baking.
- Let the casserole rest before slicing so the layers set and the slices hold together better.
- For extra flavor, sprinkle grated Parmesan over the top before serving or add fresh basil or oregano after baking.
Storage
Store any leftovers in an airtight container in the refrigerator for up to four days. To reheat, microwave individual slices for 1–2 minutes or warm in a 350°F oven until heated through. You can also freeze the casserole: wrap tightly or place in a freezer-safe container for up to two months. Thaw overnight in the refrigerator before reheating.
Serving Suggestions
Pair this casserole with a crisp green salad, roasted vegetables, or steamed broccoli for a lighter accompaniment. Garlic bread or breadsticks make it feel like a full pizza night. Finish with a sprinkle of red pepper flakes, grated Parmesan, or chopped fresh basil for added brightness.
Recipe FAQs
Yes. Brown the ground beef and let it cool, then assemble the casserole and cover it in the refrigerator. Bake it the day you plan to serve it.
How do I store leftovers?
Store leftovers in clean, airtight containers in the refrigerator. Use glass, plastic, or zip-top bags—whatever you have on hand is fine as long as it seals well.
What defines a casserole?
A casserole is typically a one-dish meal made by layering starches (like rice or pasta), proteins, vegetables, and a sauce in a baking dish, then baking until everything is cooked and melded together. They’re convenient for feeding a group and can often be prepared ahead of time.
