Ingredients You’ll Need

Each ingredient really plays a part here: from pasta that holds sauce beautifully, to a trio of cheeses that melt into absolute perfection. Here are some tips on picking the best ingredients for your Tik Tok Million Dollar Spaghetti Casserole Recipe.

• Angel Hair Pasta or Spaghetti: I love using angel hair for its delicate texture, but spaghetti works just as well if you prefer thicker strands.
• Marinara Sauce: Grab a good-quality jar or make your own for deeper flavor — it’s the base of that savory meat layer.
• Ground Beef (80/20): The right fat content keeps the meat juicy and flavorful without drying out.
• Hot Italian Sausage: I often go mild for family dinners, but if you like a kick, hot is the way to go.
• Onion and Green Bell Pepper: These add great texture and a fresh bite to balance the richness.
• Garlic Cloves: Using lots of garlic amps up the aroma and depth of flavor — don’t skimp here!
• Butter: Essential for the creamy alfredo sauce, so don’t substitute with margarine or oil.
• Heavy Cream: This is where the sauce gets that luscious smoothness.
• Parmesan Cheese: Freshly grated is a game changer — it melts better and tastes so much fresher.
• Cream Cheese: Adds a subtle tang and extra creaminess to the sauce.
• Italian Seasoning: Just a sprinkle will bring all the flavors together beautifully.
• Mozzarella, Fontina, and Provolone Cheese: The triple cheese topping is what elevates this from yummy to irresistible.
• Salt and Freshly Cracked Pepper: Always season thoughtfully — it pulls the whole dish together.
• Fresh Parsley: For a bright, fresh pop on top after baking.

Variations

I like to mix things up depending on my mood or what’s in the fridge. This recipe is super forgiving, so don’t hesitate to make it your own by swapping ingredients or adding extra touches.

• Vegetarian Variation: I swapped out the meat for sautéed mushrooms and zucchini once, and honestly, it was just as satisfying.
• Cheese Swaps: Sometimes I use gouda or sharp cheddar instead of provolone for a smoky hint that my family adores.
• Spicy Kick: Adding a pinch of red pepper flakes into the marinara sauce gives it a subtle heat that wakes up the whole dish.
• Gluten-Free: Use gluten-free pasta, and just be sure to check your marinara sauce for hidden gluten.

How to Make Tik Tok Million Dollar Spaghetti Casserole Recipe

Step 1: Whip Up That Creamy Alfredo Sauce

First thing’s first, get a big pot of salted water boiling for your pasta. Meanwhile, melt 6 tablespoons of butter over medium-low heat in a large skillet, and throw in half your minced garlic. Let it sauté gently until fragrant — that garlicky aroma is the secret to the sauce’s depth. Next, pour in the heavy cream and bring it to a low boil, then reduce it to a simmer. Stir it occasionally for about five minutes until it thickens slightly. Then, whisk in the freshly grated parmesan and softened cream cheese until everything melts smoothly into a luscious sauce. Season with salt, freshly cracked pepper, and if you like a little heat, a pinch of red pepper flakes. It’s okay if your sauce seems a little runny now; remember, it thickens more as it cools and bakes.

Step 2: Cook the Pasta and Coat with Alfredo

Cook your angel hair pasta or spaghetti until just al dente according to package instructions. Drain it well, then toss it back into your pot. Pour over that dreamy alfredo sauce and stir gently so every noodle’s coated in creamy goodness. Pro tip: tossing the pasta directly in the pot helps it soak up the sauce better than layering later.

Step 3: Brown the Meat and Veggies

Clean out your skillet and heat a tablespoon of olive oil over medium heat. Add the ground beef and Italian sausage, breaking it up as it browns. After about two minutes, toss in your diced onion, green bell pepper, and the rest of the minced garlic. Sauté everything together until the veggies soften and the meat’s cooked through. Pour in the marinara sauce along with Italian seasoning, salt, and pepper to taste — stir it well so the sauce and meat blend perfectly.

Step 4: Assemble and Bake Your Casserole

Grease a large cast iron skillet or a 9×13 casserole dish — I like cast iron because of the even heat it gives. Spread the alfredo-coated pasta evenly across the bottom, then spoon the rich marinara meat sauce over it like a generous layer. Smooth it out with a spatula for even coverage. Finally, pile on the shredded mozzarella, fontina, and provolone cheeses for that melty, golden top. Bake at 400°F (200°C) for 20 minutes. If you want that bubbly, slightly crispy cheese crust, pop it under the broiler for 3-5 minutes, but keep a close eye on it so it doesn’t burn.

How to Serve Tik Tok Million Dollar Spaghetti Casserole Recipe

Garnishes

I like to sprinkle freshly chopped parsley over the top right before serving — it adds a bright pop of color and a fresh herbal note that balances the richness. Sometimes I squeeze a little fresh lemon over my portion for an unexpected zing that really wakes up the flavors.

Side Dishes

My favorite sides to serve with this are a crisp green salad with vinaigrette to cut some of the richness and roasted garlic bread for dipping—you can never have too much garlic, right?

Creative Ways to Present

For special occasions, I’ve baked this casserole in individual ramekins for a cute, personalized presentation. It looks fancy but is seriously easy and perfect for portion control at dinner parties. You could also sprinkle crispy fried onions on top for an additional crunchy texture that’s always a hit.

Make Ahead and Storage

Storing Leftovers

I usually store leftovers in an airtight container in the fridge for up to 3 days. Pro tip: let the casserole cool completely before covering—it helps prevent sogginess and keeps the flavors vibrant.

Freezing

This recipe freezes beautifully! I portion it into freezer-safe containers before baking and freeze for up to 2 months. When I’m ready to eat it, I thaw overnight in the fridge and bake as usual. Freezing before baking helps keep the textures spot-on.

Reheating

Reheat leftovers in the oven at 350°F (175°C) until warmed through — about 15-20 minutes. To prevent drying out, cover loosely with foil, then uncover at the end to crisp up the cheese topping again.
