Monterey Spaghetti Bake – Creamy, Cheesy Family Favorite

Some recipes don’t just feed a family—they bring everyone to the table. Monterey Spaghetti Bake is exactly that kind of dish. Warm, creamy, and layered with comforting flavors, this baked spaghetti casserole has been a longtime favorite in kitchens where simple ingredients and big portions matter most. It’s the kind of meal that fills the house with the smell of bubbling cheese and makes everyone wander into the kitchen asking, “Is it ready yet?”

What sets this spaghetti bake apart from classic baked pasta dishes is its unmistakably creamy heart. Instead of relying solely on tomato sauce, this recipe blends sour cream, cream cheese, and butter into the spaghetti, creating a rich, velvety base that feels indulgent without being complicated. Topped with a savory meat sauce and finished with melted Monterey Jack cheese, it bakes into a golden, comforting casserole that’s both nostalgic and incredibly satisfying.

This is a true family favorite for a reason. It’s budget-friendly, feeds a crowd, reheats beautifully, and works just as well for busy weeknights as it does for potlucks and casual gatherings. If you’re looking for a no-fuss dinner that delivers maximum comfort, Monterey Spaghetti Bake deserves a permanent spot in your recipe rotation.

Ingredients:

For the Spaghetti Base

• 12 ounces spaghetti
• 4 tablespoons butter
• 1 cup sour cream
• 4 ounces cream cheese, softened
• ½ teaspoon salt
• ¼ teaspoon black pepper

For the Meat Sauce

• 1 pound ground beef
• 1 small onion, finely chopped
• 3 cloves garlic, minced
• 2 cups tomato sauce
• 1 teaspoon Italian seasoning
• ½ teaspoon paprika
• ½ teaspoon salt
• ¼ teaspoon black pepper

For the Topping

• 2 cups shredded Monterey Jack cheese
• 2 tablespoons fresh parsley, chopped (optional)

Instructions:

1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish and set aside.
2. Cook the spaghetti in a large pot of salted water according to package instructions until al dente. Drain well and return to the pot.
3. While the spaghetti cooks, brown the ground beef in a large skillet over medium heat. Add the chopped onion and cook for 4–5 minutes until softened.
4. Stir in the garlic and cook for 30 seconds until fragrant. Drain excess fat if needed.
5. Add tomato sauce, Italian seasoning, paprika, salt, and black pepper to the skillet. Simmer for 8–10 minutes, allowing the flavors to blend. Remove from heat.
6. To the warm spaghetti, add butter, sour cream, cream cheese, salt, and pepper. Toss gently until the butter melts and everything is evenly coated in a creamy sauce.
7. Spread half of the creamy spaghetti mixture evenly into the prepared baking dish.
8. Spoon half of the meat sauce over the spaghetti layer.
9. Repeat with the remaining spaghetti and meat sauce, creating two layers.
10. Sprinkle shredded Monterey Jack cheese evenly over the top.
11. Bake uncovered for 25–30 minutes, or until the casserole is heated through and the cheese is melted and lightly golden.
12. Let rest for 5–10 minutes before serving. Garnish with chopped parsley if desired.

Tips & Tricks:

• Cook spaghetti just until al dente so it doesn’t become mushy after baking.
• Soften cream cheese fully for the smoothest texture.
• Let the casserole rest before slicing to help it set.
• For extra browning, broil the casserole for the last 2 minutes.

Variations:

• Swap ground beef for ground turkey or Italian sausage.
• Add sautéed mushrooms or bell peppers to the meat sauce.
• Use a blend of Monterey Jack and mozzarella for extra stretch.
• Add a pinch of red pepper flakes for gentle heat.

Serving Suggestions:

• Serve with garlic bread or warm dinner rolls.
• Pair with a crisp green salad to balance the richness.
• Perfect for family dinners, potlucks, or freezer meals.
• Add steamed green beans or broccoli on the side.

Storage Information:

• Store leftovers in an airtight container in the refrigerator for up to 4 days.
• Freeze unbaked or baked casserole for up to 3 months.
• Reheat in the oven at 325°F until warmed through, or microwave individual portions.

FAQ:

• Can I make this ahead of time? Yes, assemble and refrigerate up to 24 hours before baking.
• Is Monterey Jack required? It’s recommended, but mozzarella or Colby Jack work well too.
