Ingredients You’ll Need

Grab these bad boys—serves 6-8 hungry humans. No exotic hunts required; most lurk in your fridge already.

• 4 cups grated zucchini (about 4 medium ones—squeeze out the water like it’s personally offended you)
• 2 cups shredded mozzarella cheese (the good melty kind, not that pre-shredded sawdust)
• 1 cup shredded cheddar (for extra sharpness—trust me, it slaps)
• 1/2 cup grated Parmesan (fresh if you’re fancy, green can if you’re me)
• 2 large eggs (whip ’em up to bind this magic)
• 1/4 cup almond flour or regular flour (keeps it sturdy without the carb coma)
• 1 cup pizza sauce (jarred is fine— Rao’s if you wanna flex)
• Your fave pizza toppings (pepperoni slices, bell peppers, olives, mushrooms—go wild, 2-3 cups total)
• 1 tsp Italian seasoning (or just oregano if that’s your vibe)
• 1/2 tsp garlic powder (because garlic fixes everything)
• Salt and pepper to taste (don’t skimp—zucchini’s bland without it)
• Optional: crushed red pepper for that spicy kick

Total time? 10 mins prep, 40 mins bake. Calories per serving? Around 300—ish. You’re welcome.

Step-by-Step Instructions

Fire up that oven to 375°F (190°C) and grease a 9×13 baking dish. Let’s make magic happen, one easy step at a time.

1. Grate and drain the zucchini. Shred those suckers with a box grater or food processor. Toss ’em in a clean kitchen towel and squeeze like you’re wringing out your gym clothes—get rid of excess moisture or it’ll be a soggy mess. Takes 2 minutes, changes everything.
2. Mix the base. In a big bowl, combine drained zucchini, eggs, almond flour, Parmesan, Italian seasoning, garlic powder, salt, and pepper. Stir until it sticks together like the world’s best veggie Play-Doh. Spread evenly in your greased dish—pat it down firm.
3. Pre-bake the crust. Pop it in the oven for 15-20 minutes until it firms up and turns golden. You’re basically blind-baking a zucchini crust. Pull it out; it should hold its shape like a champ.
4. Sauce it up. Slather on that pizza sauce generously. Layer mozzarella and cheddar next—don’t hold back. Pile on toppings: pepperoni first for grease distribution, then veggies. Finish with a cheese blanket and extra parm sprinkle.
5. Bake to bubbly perfection. Back in the oven for 20-25 minutes, until cheese bubbles and browns. Broil for 1-2 minutes if you crave crispy edges (watch it like a hawk—no burnt offerings). Let it cool 5 minutes before slicing. Dive in with a spatula.

Pro tip: Serve with a side salad to feel virtuous, but we both know you’ll skip it.

Common Mistakes to Avoid

Nobody’s perfect, but these slip-ups turn your casserole into a crime scene. Learn from my kitchen fails.

• Skipping the squeeze: Wet zucchini = watery disaster. Rookie move—always drain like your life’s on the line.
• Overloading toppings: Greasy pepperoni mountains make it sink. Keep it balanced or mourn your soggy dreams.
• Low-and-slow baking: Impatient? It won’t set. Stick to 375°F—no cheating with higher temps unless you love smoke alarms.
• Forgetting to pre-bake: Straight to sauce? You’ll get mush. That 20-minute crust step is non-negotiable.
• Cutting too soon: Hot casserole = cheese avalanche. Wait 5 minutes, you eager beaver.

Dodge these, and you’re golden. IMO, the squeeze is the real MVP.

Alternatives & Substitutions

Not everyone has zucchini riots in their garden—here’s how to hack it without rage-quitting.

• No zucchini? Grate cauliflower or yellow squash. Same vibe, slightly different chew—cauli’s my low-carb fave.
• Dairy-free? Swap cheeses for vegan shreds (Daiya works). Use flax eggs (1 tbsp flax + 3 tbsp water per egg).
• Gluten-full life? Regular flour instead of almond. Or go keto with coconut flour (add an extra egg).
• Meatless Monday? Ditch pepperoni for plant-based sausage or extra veggies. Mushrooms + spinach = umami bomb.
• Spice level up? Add jalapeños or swap sauce for buffalo—turn it into game-day gold.

Personal take: Pepperoni’s non-negotiable, but sub freely. Experiment; it’s forgiving.

FAQ’s

Can I make this ahead of time?

Heck yeah! Assemble, cover, and fridge up to 24 hours. Bake fresh or reheat at 350°F. Freezes like a dream—thaw overnight first.

Is it really kid-friendly?

Totally. They devour the cheese and toppings, zucchini hides like a ninja. Sneak those veggies in without the veggie war.

How do I store leftovers?

Fridge in airtight container for 3-4 days. Reheat in oven (not microwave—keeps crisp). Or freeze slices for pizza emergencies.

Can I use margarine instead of butter? (Wait, no butter here!)

No butter needed, but if you’re tweaking, stick to oil for greasing. Margarine? Sure, but real oil tastes better—don’t cheap out your soul.

What if my crust doesn’t firm up?

More squeeze, less moisture! Or bake longer next time. Pat it firmer pre-bake. Happens to the best of us.

Can I add meat other than pepperoni?

Load up sausage, ground beef (pre-cook it), or bacon bits. Just drain fat—nobody wants an oil slick.

Is this keto or low-carb?

Yep, under 10g net carbs per serving with almond flour. Keto win—pizza without the guilt trip.
