Tips for success

For the best cheese pull, use a sharp cheddar and shred it yourself. The natural moisture in freshly shredded cheese melts more smoothly than pre-shredded.

Also, let the casserole rest for a full 5 minutes after baking—this allows the cheese to set slightly, making it easier to serve and more dramatic when you lift a forkful.

To make the dish ahead, assemble the casserole completely, cover it, and refrigerate for up to 24 hours.

When ready to bake, add about 10 minutes to the baking time. This is a great make-ahead meal for busy weeks or when feeding a crowd.

Variations

Spicy Taco Spaghetti: Add 1-2 diced jalapeños or a teaspoon of crushed red pepper flakes to the beef while cooking. Use pepper jack cheese instead of cheddar for extra heat.
Vegetarian Version: Replace the ground beef with 1 lb of cooked lentils or a plant-based ground meat substitute. Cook as directed, omitting the meat, and reduce the baking time by 5 minutes.
Mexican Street Corn Twist: Stir 1 cup of corn kernels and 1/4 cup of chopped cilantro into the sauce before combining with the pasta. Top with crumbled cotija cheese after baking.
BBQ Taco Spaghetti: Swap the taco seasoning for 2 tablespoons of BBQ rub and add 1/2 cup of BBQ sauce to the meat sauce. Use smoked cheddar for a deeper flavor.

Storage and make-ahead

Fridge: Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven until hot.
Freezer: Freeze the baked, cooled casserole in a covered container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheat: Reheat individual portions in the microwave for 1-2 minutes, or in a 350°F (175°C) oven for 10-15 minutes until warmed through.

Store leftover casserole in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or in a 350°F (175°C) oven until warmed through.

Assemble the casserole up to 24 hours in advance, cover, and refrigerate. When ready to bake, add 10-15 minutes to the cooking time. The casserole can also be baked, cooled, and frozen for up to 3 months.

Serving ideas

Serve the casserole hot, straight from the baking dish, with a sprinkle of fresh parsley. It pairs well with a simple green salad or roasted vegetables.

For extra toppings, offer sour cream, sliced jalapeños, or avocado—though the casserole is delicious on its own.

This is a family-style dish, so bring the baking dish to the table and let everyone serve themselves.

The cheese pull when you lift the first spoonful is always a crowd-pleaser. Leftovers are great for lunch the next day.

Frequently asked questions

Can this casserole be made gluten-free?

Yes, simply use gluten-free spaghetti and ensure your taco seasoning is gluten-free. Many brands are, but check the label. The rest of the ingredients are naturally gluten-free.

Can this dish be frozen?

Yes, you can freeze the baked casserole. Let it cool completely, then wrap tightly or place in an airtight container. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

How can the recipe be made spicier?

Add diced jalapeños, a dash of hot sauce, or use a spicy taco seasoning. You can also mix in some chopped chipotle peppers in adobo sauce for a smoky heat.

What can be used instead of cream cheese?

For a similar creamy texture, use full-fat cream cheese is best, but you can substitute with Greek yogurt or mascarpone. Keep in mind that Greek yogurt may curdle if heated too high, so stir it in off the heat.

Why does the casserole sometimes turn out dry?

Overbaking is the most common cause. Bake just until the cheese is melted and the edges are bubbling, and let it rest for 5 minutes. Also, make sure the spaghetti is well coated with the sauce before baking.

Cheesy Taco Spaghetti Casserole: One-Pan Dinner

Prep 20 minCook 45 minTotal 1 h 5 minServes 8

Ingredients

12 oz spaghetti
1 lb ground beef
1 oz taco seasoning
4 oz cream cheese, softened
1/2 cup sour cream
15 oz tomato sauce
2 cups shredded cheddar cheese
2 tbsp chopped fresh parsley

Instructions

Bring a large pot of salted water to a boil. Cook the spaghetti according to package directions until al dente. Drain and set aside. In a large skillet over medium-high heat, cook the ground beef, breaking it up with a spoon, until browned and no longer pink. Drain any excess fat. Stir in the taco seasoning and cook for 1 minute until fragrant.
Reduce the heat to low. Add the cream cheese and sour cream to the skillet with the beef, stirring until melted and smooth. Pour in the tomato sauce and stir to combine. Let the sauce simmer gently for 5 minutes to meld the flavors.
Add the drained spaghetti to the skillet with the beef sauce. Toss everything together with tongs until the pasta is fully coated in the creamy sauce.
Preheat the oven to 350°F (175°C). Transfer the spaghetti mixture to a 9x13-inch baking dish and spread it into an even layer.
Sprinkle the shredded cheddar cheese evenly over the top of the casserole.
Bake the casserole for 20-25 minutes, until the cheese is melted, golden, and the edges are bubbling. The internal temperature of the casserole should reach 165°F (74°C) to ensure it is heated through.
Remove the casserole from the oven and let it rest for 5 minutes. Sprinkle with chopped fresh parsley before serving.
