Introduction

Baked Cream Cheese Spaghetti Casserole is the ultimate comfort-food dish — a perfect fusion between classic Italian spaghetti and rich, creamy American–style casseroles. This dish transforms simple pantry staples into something deeply satisfying: tender pasta coated in a silky cream-cheese sauce, covered with a savory meat marinara, and finished in the oven until bubbling and lightly golden.

Whether you’re cooking for a family dinner, hosting guests, or meal-prepping for the week, this casserole delivers bold flavor, hearty texture, and that “homey” feel everyone loves. It’s budget-friendly, kid-friendly, reheats beautifully, and can be customized in dozens of delicious ways.

The History

Spaghetti casseroles became popular in the United States during the mid-20th century, especially as canned tomatoes, dried pasta, and block cream cheese became affordable household staples. Home cooks discovered that combining pasta with creamy bases (cream cheese, ricotta, or condensed soups) created dishes that stretched ingredients, fed large families, and reheated well.

This recipe, often called “Million Dollar Spaghetti,” evolved into many versions — some baked with layers like lasagna, others mixed completely. The cream-cheese version gained fame because:

• Cream cheese melts into a luxurious, velvety sauce
• It balances acidity from tomato sauce
• It stays moist even after baking
• It gives the casserole a signature richness not found in plain spaghetti dishes

Today it’s a beloved weeknight classic and potluck favorite.

Ingredients Breakdown (What Each Ingredient Does)

Step-by-Step Recipe (Very Detailed)

Step 1 — Cook the Spaghetti

1. Bring a large pot of salted water to a boil.
2. Add spaghetti and cook until al dente (about 8–9 minutes).
3. Drain well — do NOT overcook or it will become mushy in the oven.

Tip: Toss the drained pasta with a teaspoon of olive oil to prevent sticking.

Step 2 — Make the Meat Sauce

1. In a skillet over medium heat, brown 1 lb (450g) ground beef or Italian sausage.
2. Drain excess fat.
3. Add 1 chopped onion and cook until softened (3–4 minutes).
4. Stir in 3–4 cloves minced garlic and cook 1 minute.
5. Pour in 24 oz (700g) marinara sauce.
6. Season with:
   • 1 tsp Italian seasoning
   • Salt + pepper to taste
   • Optional: a pinch of chili flakes

Simmer for 8–10 minutes to deepen the flavor.

Step 3 — Make the Cream Cheese Pasta Base

1. In a large mixing bowl, add:
   • 8 oz (225g) cream cheese, softened
   • ½ cup sour cream (optional for extra creaminess)
   • ½ cup Parmesan
   • 1 tsp garlic powder
2. Add the warm cooked spaghetti on top.
3. Toss until every strand is coated in creamy goodness.

The heat from the pasta melts the cream cheese and creates a luxurious sauce.

Step 4 — Assemble the Casserole

1. Grease a baking dish with butter.
2. Add the cream-cheese coated spaghetti as the bottom layer.
3. Spread the meat sauce evenly on top.
4. Sprinkle generously with:
   • 1–2 cups shredded mozzarella
   • Extra Parmesan if desired

Step 5 — Bake

• Preheat oven to 350°F (175°C).
• Bake uncovered for 20–25 minutes, or until:
  • The cheese is melted
  • The edges are bubbling
  • The top is lightly golden

Let it rest for 5–10 minutes before slicing so the layers hold together.

Tips for the Best Possible Casserole

⭐ 1. Use hot pasta when mixing with cream cheese

It melts instantly and creates the perfect coating.

⭐ 2. Don’t overcook the spaghetti

It finishes cooking in the oven.

⭐ 3. Add a splash of pasta water if needed

Helps emulsify the creamy sauce.

⭐ 4. Shred your own mozzarella

It melts better than pre-shredded (which contains anti-caking agents).

⭐ 5. Let it rest before cutting

This prevents a messy plate and allows layers to set.
