Ingredients You’ll Need
The best part about this recipe is it doesn’t require a lot of crazy ingredients. Here’s what you’ll need:
Essential Ingredients
- 2–3 medium zucchinis, thinly sliced
- 1 lb (450 g) ground beef or Italian sausage
- 1 cup marinara or pizza sauce (sugar-free if you’re feeling fancy)
- 2 cups shredded mozzarella cheese
- 1/2 cup grated Parmesan
- 1/2 tsp garlic powder
- 1/2 tsp Italian seasoning
- Salt and pepper to taste
Optional Toppings
- Sliced olives, bell peppers, or mushrooms
- Crushed red pepper flakes for a spicy kick
- Fresh basil for garnish
Pro tip: I usually add a sprinkle of oregano on top—it makes the casserole taste like it came straight from a pizzeria.
Step-by-Step Instructions
This casserole is easy, forgiving, and hands-on without being intimidating. Follow these steps for pizza-flavored perfection.
Step 1: Prep the Zucchini
- Wash and thinly slice zucchinis.
- Lay slices on a paper towel and sprinkle lightly with salt to remove excess water.
- Let them sit for 10 minutes, then pat dry.
Ever wondered why zucchini casseroles get watery? Blotting the water is key—trust me, it makes a world of difference.
Step 2: Cook the Meat
- Brown your ground beef or Italian sausage in a skillet over medium heat.
- Add garlic powder, Italian seasoning, salt, and pepper.
- Drain excess fat if needed.
The meat should be fully cooked and well-seasoned—it’s the base that gives the casserole its hearty flavor.
Step 3: Layer the Casserole
- Preheat oven to 375°F (190°C).
- Spread a thin layer of pizza sauce on the bottom of a casserole dish.
- Add a layer of zucchini slices.
- Sprinkle half of the cooked meat over the zucchini.
- Add half of the mozzarella and Parmesan.
- Repeat layers, finishing with cheese on top.
Layering keeps every bite balanced—you get zucchini, cheese, and meat together, not random cheese clumps.
Step 4: Bake
- Cover casserole with foil and bake for 25 minutes.
- Remove foil and bake for an additional 10–15 minutes until cheese is bubbly and golden.
- Let rest for 5 minutes before serving.
FYI, resting is crucial—skip it, and the casserole slides off the plate like a cheesy landslide.
Cheese Makes Everything Better
Cheese is the MVP here. Don’t skimp.
Best Cheese Choices
- Mozzarella: Melty, stretchy, classic pizza vibe
- Parmesan: Adds a salty, nutty flavor
- Optional cheddar: Sharpness and depth
I personally mix mozzarella and Parmesan. It creates melty goodness with a little crisp on top that feels indulgent without being over the top.
Why Zucchini Works Perfectly
Zucchini isn’t just a low-carb replacement—it’s actually delicious when cooked right.
- Tender, not mushy: Pre-salting removes excess water.
- Mild flavor: It soaks up marinara and cheese flavors.
- Adds nutrients: Fiber, vitamins, and a little crunch.
If you’ve ever avoided zucchini because it tastes “bland,” this recipe might convert you. The cheese and sauce do all the heavy lifting.
Optional Add-Ons for Extra Flavor
Want to go beyond the classic? Try these:
- Pepperoni slices: Yes, like pizza!
- Roasted red peppers: Adds sweetness and color
- Mushrooms: Earthy, umami goodness
- Crushed red pepper: Light spice without overpowering
IMO, pepperoni + mushrooms = adult pizza heaven in casserole form.
Tips for the Best Zucchini Pizza Casserole
Here’s where a little know-how saves you from soggy or bland results:
- Don’t overcook zucchini before layering—it’ll release water in the oven.
- Season each layer—a pinch of salt and Italian seasoning goes a long way.
- Cheese strategically—layering cheese ensures melty goodness throughout.
- Let it rest—seriously, it sets beautifully after 5 minutes.
Ever rushed a casserole out of the oven? It’s a gooey, runny mess. Trust me on this one.
Serving Suggestions
This casserole is filling on its own, but pairing it with a few sides takes it to next-level dinner:
- Simple salad: Mixed greens, olive oil, and balsamic
- Garlic bread (low-carb version): Because carbs are fun sometimes
- Roasted veggies: Keeps it healthy without extra effort
Or, just grab a fork and dive in—zero shame here. 🙂
Storing and Reheating
One of the best things about this casserole? Leftovers taste just as good.
Storage
- Refrigerate in an airtight container for 3–4 days
- Freeze portions for up to 3 months
Reheating
- Microwave individual servings for 2–3 minutes
- Bake at 350°F for 10–15 minutes to refresh texture
Pro tip: sprinkle extra cheese on top before reheating—it melts beautifully and tastes fresh.
Why This Casserole is Perfect for Families and Meal Prep
Here’s the truth—weeknights are chaotic. This casserole is a life-saver:
- Quick to prep: 15–20 minutes
- Kid-approved: Pizza vibes without processed ingredients
- Freezer-friendly: Perfect for meal prep or busy weeks
I often make a double batch—one for dinner, one for lunch the next day. It’s like having pizza on standby.
Common Mistakes to Avoid
Even the best recipes fail if you slip on these:
- Overcrowding zucchini → soggy layers
- Skipping seasoning → bland casserole
- Not pre-salting zucchini → watery dish
- Not resting → messy slices
Follow these rules, and you’ll get a cheesy, flavorful, perfectly set casserole every time.
Why Zucchini Pizza Casserole Beats Traditional Pizza
- Lower in carbs → guilt-free indulgence
- Packed with veggies → sneaky nutrition
- Customizable → swap meats, cheeses, or veggies freely

Seriously, it’s comfort food without the crash afterward.
