Instructions: How To Make the Best Casserole Recipe

This casserole bakes up cheesy, hearty, and bursting with pizza flavor—without the dough. It’s a two-step process: first, bake your zucchini base, then top with sauce, meat, and (of course) more cheese.

Step-by-Step:

1. Preheat & Prep Zucchini:
   Preheat oven to 400°F. Place shredded zucchini in a colander, sprinkle with salt, and let it sit for 10 minutes. Squeeze out as much moisture as possible (seriously, this step matters!).

2. Mix the Zucchini Base:
   In a large bowl, combine the zucchini, eggs, Parmesan, and half the mozzarella and cheddar. Mix until it holds together.

3. Make the “Crust”:
   Press the zucchini mixture firmly into a greased 13×9-inch baking dish. Bake for 20 minutes, just until set.

4. Prepare the Topping:
   Meanwhile, cook ground beef and onion in a skillet over medium heat until the beef is browned and no longer pink. Drain off excess fat. Stir in tomato sauce.

5. Layer It Up:
   Spoon the beef mixture over the baked zucchini base. Sprinkle with the rest of the cheeses and the chopped bell pepper.

6. Bake Again:
   Return to the oven and bake another 20 minutes, until bubbly and golden on top.
7. Cool & Serve:
   Let it cool for 5-10 minutes so it slices up nice. Serve hot and watch it disappear!

Zucchini Prep Tips: How to Avoid a Soggy Casserole

• Shred zucchini (no need to peel), salt, and let sit in a colander for 10 minutes
• Squeeze out all the moisture with a towel or cheesecloth—really press!
• Zucchini should be dry and crumbly, not wet
• Works for frozen zucchini too—thaw, drain, and squeeze

Let’s Talk Cheese: The Meltier, the Better

Freshly grated cheese melts best, but any works in a pinch.

• Parmesan: Nutty, salty flavor
• Mozzarella: Classic stretch
• Cheddar: Sharp, tangy bite
• Try provolone, Asiago, or Romano for a fancier touch

Serving Ideas and Storage Tips

• Serve With: Garlic bread, simple salad, or just a fork—this is comfort food.
• Leftovers: Store in the fridge for up to 4 days. Reheat in the microwave or oven.
• Freeze For Later: Cool completely, wrap tightly, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.

Make It Your Own: Pizza Night Gets a Casserole Upgrade

You can totally riff on this recipe depending on what’s in your fridge or what your family loves. Here are some ideas:

• Swap ground beef for Italian sausage or turkey.
• Top with pepperoni or Canadian bacon before baking for a “meat lover’s” twist.
• Go all-in on veggies with mushrooms, spinach, or olives.
• Garnish with fresh basil or a sprinkle of red pepper flakes for extra zip.
