Ingredients You’ll Need

Gather these bad boys—most are pantry staples, so no emergency grocery run required. Serves a crowd (8-10), FYI.

• 1 lb (450g) rotini or penne pasta – sturdy enough to hold all that saucy glory.
• 2 jars (24 oz each) pizza sauce – the cheap kind works; we’re not snobs here.
• 2 cups shredded mozzarella cheese – go for the fresh ball if you wanna feel fancy.
• 1 cup shredded cheddar cheese – for that extra gooey sharpness.
• 1 package (8 oz) pepperoni slices – mini ones if you hate big bites (personal fave).
• 1 lb ground Italian sausage (or ground beef) – browned for meaty goodness.
• 1 green bell pepper, diced – adds crunch without overpowering.
• 1 small onion, diced – sweetens things up.
• 2 cups sliced mushrooms (canned or fresh) – optional, but they soak up sauce like champs.
• 1 tsp Italian seasoning – lazy hack for herby vibes.
• 1/2 tsp garlic powder – because real garlic is messy.
• Salt and pepper to taste – duh.
• Fresh basil or oregano for topping (optional, but makes you look pro).

Step-by-Step Instructions

Cook with confidence—these steps are dummy-simple. Preheat your oven to 375°F (190°C) now, rookie.

1. Boil the pasta. Grab a big pot, salt the water like the ocean, and cook pasta al dente (about 8 minutes). Drain it quick—nobody likes soggy mush.
2. Brown the meat. In a skillet over medium heat, crumble and cook sausage (or beef) until browned, about 5-7 minutes. Drain the grease unless you want a heart attack special.
3. Sauté the veggies. Toss diced onion, bell pepper, and mushrooms into the same skillet. Cook 3-4 minutes until soft. Stir in Italian seasoning, garlic powder, salt, and pepper. Smells like heaven already, right?
4. Mix the magic. In a massive bowl (or your biggest baking dish), combine cooked pasta, meat, veggies, and pizza sauce. Stir until everything’s coated—get those hands in there for fun.
5. Layer it up. Dump half the mix into a greased 9×13-inch baking dish. Sprinkle 1 cup mozzarella and 1/2 cup cheddar. Add half the pepperoni. Repeat layers: rest of mix, more cheese, all remaining pepperoni on top.
6. Bake to bubbly bliss. Pop in the oven for 25-30 minutes until cheese is golden and melty. Broil for 2 minutes if you want crispy edges (watch it like a hawk!).
7. Rest and serve. Let it chill 5 minutes so it doesn’t lava-flow your mouth. Garnish with basil if you’re extra.

Boom—dinner’s served!

Common Mistakes to Avoid

Listen up, because we’ve all been there. Dodge these pitfalls for casserole perfection.

• Skipping the pasta al dente step. Overcook it, and you’ll end up with gluey sadness. Test early—it finishes cooking in the oven.
• Forgetting to preheat. Cold oven = uneven bake and rubbery cheese. Set it and forget it before starting.
• Overloading toppings. Too much stuff sinks the dish. Stick to 2-3 cups max extras.
• Diving in too hot. That steaming scoop? Patience, grasshopper—wait 5 minutes or burn your tongue forever.
• ** skimping on cheese.** Why even live? Generous handfuls only, or it’s not pizza.

Rookie moves, but now you’re armed.

Alternatives & Substitutions

Not everyone has a pepperoni shrine in their fridge. No sweat—swap freely. IMO, these tweaks keep it rocking.

• Veggie-only version: Ditch meat for extra mushrooms, spinach, or zucchini. Still feeds a crowd, zero guilt.
• Pasta swap: Use rigatoni for chunkier bites or gluten-free if needed. Tortellini? Fancy upgrade.
• Sauce hack: Homemade? Blend canned tomatoes with herbs. Lazy? Ragu or Prego crushes it.
• Cheese lovers: Swap cheddar for provolone or add ricotta dollops for lasagna feels.
• Spicy kick: Turkey pepperoni or chorizo instead of sausage. Pineapple? Fight me—it’s gold.
• Make it lighter: Turkey sausage, low-fat cheese, whole wheat pasta. Tastes 90% as good, promise.

Personal tip: Go meatless on Taco Tuesday for a Mexican twist with salsa and ground turkey.

FAQ

Can I make this ahead of time?

Totally! Assemble up to 24 hours early, cover, and fridge it. Bake when ready—add 5-10 extra minutes. Freezer-friendly for 3 months too. Thaw overnight first.

Is it kid-friendly?

Kids go nuts for it—pizza in a pan? Sold. Hide veggies if picky eaters lurk, or chop finer.

How do I reheat leftovers?

Microwave single servings (1-2 minutes), or oven at 350°F for 15 minutes. Pro move: Air fryer for crispy top.

Can I use margarine instead of butter?

We didn’t use butter, genius, but if greasing the pan? Margarine works, but olive oil spray is lazier and healthier. Why complicate?

What if I hate mushrooms?

Pitch ’em! Sub black olives or broccoli. Or nothing—sauce carries the show.

Does it work in a slow cooker?

Yep, layer it in on low for 4 hours. Less crispy, more set-it-forget-it. Top with cheese last 30 minutes.

How spicy is it?

Mild as a kitten unless you amp sausage or add red pepper flakes. Customize per scoop for wimps and warriors.
