It gives you pizza vibes without the fiddly dough, and it is forgiving enough for a Tuesday night when motivation left the building.

Ingredients You’ll Need
- 4 cups shredded zucchini, because sneaky greens are the star here
- 1/2 teaspoon salt, to pull out the zucchini moisture like a pro
- 2 large eggs, the glue that holds this whole delightful mess together
- 1/2 cup grated Parmesan cheese, salty and classy
- 2 cups shredded mozzarella cheese, divided, because you need gooey and then more gooey
- 1 cup shredded cheddar cheese, for sharp cheese drama
- 1 pound ground beef, browned and ready to party
- 1/2 cup chopped onion, small pieces, big flavor
- 2 cups pizza sauce, jarred or homemade, I will not judge
- 1 green bell pepper, chopped, for crunch and color
- 1/2 cup sliced mushrooms, optional fungus that plays nice
- 1/2 teaspoon dried oregano, pizza aroma in a pinch
- 1/2 teaspoon garlic powder, or real garlic if you are feeling fancy
- 1/4 teaspoon black pepper, to keep things interesting
Step-by-Step Instructions
Place shredded zucchini in a colander, sprinkle with salt, and let sit for 30 minutes. Squeeze out excess liquid and mix with eggs and Parmesan. This keeps your crust from becoming soggy. Squeeze hard. You want it drier than a desert.
Preheat oven to 375°F (190°C) and grease a baking dish. I like a 9×13 but use what you have. Grease it well so nothing sticks.
Brown ground beef in a skillet, add onions, bell pepper, and mushrooms, and cook until soft. Break the beef up good so each bite has texture and flavor.
Stir in pizza sauce, oregano, garlic powder, and black pepper. Taste it. Add salt only if it needs it, since Parmesan and sauce bring salt too.
Press zucchini mixture into baking dish as a crust. Pat it down firmly so it holds together while baking. Think compact and confident.
Layer with half of the meat sauce, mozzarella, and cheddar, repeat layers. Finish with cheese on top for that golden, bubbly finish everyone fights over.
Bake for 30-35 minutes until bubbling and golden. Keep an eye on the top after 25 minutes. If it browns too fast, tent foil loosely.
Let rest before slicing. Give it 10 minutes to settle so your slices look neat and do not fall apart.

Common Mistakes to Avoid
- Thinking you do not need to preheat the oven. Rookie mistake. Heat matters.
- Skipping the zucchini squeeze. If you skip it you will get a watery crust. Not cute.
- Overcrowding the skillet when browning beef. The meat will steam instead of brown and you lose flavor.
- Using only one cheese. Why would you do that? Mix cheeses for depth and drama.
- Cutting into it immediately. You will regret it emotionally and visually.
Alternatives & Substitutions
- No ground beef? Use Italian sausage or ground turkey. Sausage gives a spicy kick, turkey keeps it lighter.
- Dairy free? Use vegan mozzarella and Parmesan alternatives. The texture will change but the comfort stays.
- Want more greens? Add spinach to the meat layer, saute it first so it does not weep.
- Cheese haters, is that a thing? Use a sprinkle of nutritional yeast for cheesiness without the dairy.
- Gluten free? This recipe already plays well with low carb diets. If you want absolute texture change, add a thin layer of almond flour and egg in the zucchini mixture.
My take is stick to at least two cheeses. The blend makes the casserole sing.

FAQ (Frequently Asked Questions)
Q What happens if I do not squeeze the zucchini hard enough?
A Then you end up with a soggy mess and people will ask if you tried to make soup. Squeeze like your casserole depends on it because it does.
Q Can I make this ahead of time and bake it later?
A Absolutely. Assemble it, cover it, and stash it in the fridge for up to 24 hours. Let it come to room temp for 20 minutes before baking.
Q Can I freeze leftovers?
A Sure. Cut into portions and freeze. Reheat in the oven so the cheese gets bubbly again and your taste buds wake up.
Q Can I use fresh garlic instead of garlic powder?
A Yes. Use 1 to 2 cloves minced when you cook the onions. Fresh garlic gives more bite but both work fine.
Q Do I have to brown the beef first or can I use cooked rotisserie chicken?
A You can totally swap in shredded rotisserie chicken for a lighter, quicker version. Adjust herbs to taste.
Q Is this kid friendly?
A Usually yes. Kids love pizza flavors and the shy veggie hiding tactic works wonders. Serve with a smile.
Q How do I keep the top from burning while the inside finishes?
A Tent foil loosely over the dish once the top gets golden. Remove the foil for the last 5 minutes to re-brown if needed.
