TikTok Spaghetti Casserole Ingredients
For the Main Dish
• 2 tablespoons olive oil – Great for sautéing vegetables; can switch to vegetable or canola oil if desired.
• 1 cup onion, chopped – Adds sweetness and flavor; opt for yellow or white onions for best results.
• 1/2 cup green bell pepper, chopped – Adds crunch; for a sweeter option, try red or yellow bell peppers.
• 1 tablespoon garlic, minced – Elevates the flavor profile; fresh garlic is recommended over pre-minced.
• 1 pound ground beef (80/20) – The heart of the dish; can replace it with ground turkey or plant-based alternatives for a lighter meal.
• 1 1/2 teaspoons salt – Essential for flavor enhancement; adjust based on personal taste.
• 3/4 teaspoon black pepper – Introduces a hint of spice; fresh cracked pepper enhances the taste more effectively.
• 1 tablespoon Italian seasoning – Blends herbs for depth; a mix of dried basil and oregano works well too.
• 1 1/2 (24-ounce) jars spaghetti sauce – Provides the rich red sauce base; homemade or jarred versions are both fine, just watch the sugar content.
• 1 tablespoon salt (for pasta water) – Vital for seasoning the pasta itself.
• 16 ounces spaghetti – The main carbohydrate offering; swap for any pasta shape or gluten-free version if needed.
For the Alfredo Sauce
• 1/2 cup (1 stick) butter – Adds richness; margarine or plant-based spread can be substituted.
• 4 cloves garlic, minced (for Alfredo) – Delivers deep flavor; fresh garlic is best!
• 1 tablespoon all-purpose flour – Helps thicken the sauce; cornstarch can be used for gluten-free diets.
• 2 cups heavy cream – Creates that creamy texture; half-and-half or non-dairy cream will lighten the flavor but can work.
• 1 1/2 cups parmesan cheese – Delivers flavor and helps with sauce consistency; freshly shredded is ideal.
For the Topping
• 2 cups mozzarella – Melts beautifully to provide that gooey texture; enjoy exploring cheddar cheese as a flavorful substitute.
How to Make TikTok Spaghetti
Preheat Oven: Set your oven to 350°F (177°C) and prepare a 9×13-inch baking dish by spraying it with non-stick cooking spray for easy cleanup.
Sauté Vegetables: Heat the olive oil in a skillet over medium heat. Add the chopped onions and green bell pepper; sauté until they become translucent, about 5-7 minutes. Incorporate the minced garlic and cook until fragrant, around 1 minute.
Cook Beef: Add the ground beef to the skillet, breaking it apart as it cooks. Cook until there are no pink spots remaining, about 7-10 minutes. Drain any excess grease to keep the dish from being too oily.
Combine Red Sauce: Stir in the salt, black pepper, Italian seasoning, and spaghetti sauce into the cooked beef mixture. Mix well and set aside to let the flavors meld.
Prepare Pasta: While the beef mixture is cooking, bring a large pot of salted water to a boil. Cook the spaghetti according to the package instructions until al dente, then drain and set aside.
Make Alfredo Sauce: In a separate saucepan, melt the butter over medium heat. Add the minced garlic and cook for about 1 minute. Sprinkling in the flour, stir continuously for about 2 minutes, then gradually whisk in the heavy cream. Bring to a gentle simmer, then stir in the parmesan cheese until melted and smooth.
Mix Pasta & Sauce: Combine the drained spaghetti with the Alfredo sauce, making sure each strand is generously coated. Spread this mixture evenly in the prepared baking dish.
Layer Sauces: Pour the red sauce mixture over the spaghetti layer without mixing them. Top generously with mozzarella cheese to create a delightful, cheesy crust.
Bake: Place the casserole in the preheated oven and bake for about 30 minutes, or until the cheese is bubbly and golden brown.
Serve: Let the casserole cool for about 10 minutes before serving. Garnish with parsley and extra Italian seasoning for color and flavor.
Optional: Serve with a sprinkle of red pepper flakes for an extra kick!
