- 1 lb ground beef (or Italian sausage for extra flavor)
- 1 small yellow onion, finely diced
- 3 cloves garlic, minced
- 1 (24 oz) jar marinara sauce (or 3 cups homemade)
- 8 oz cream cheese, softened and cubed
- ½ cup sour cream or Greek yogurt
- ½ tsp Italian seasoning
- ¼ tsp red pepper flakes (optional)
- Salt & black pepper, to taste
For the Topping:
- 1½ cups shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- Fresh parsley, chopped (for garnish)
🧀 Pro tip: Use full-fat cream cheese—low-fat versions can make the sauce grainy.
Step-by-Step Instructions
1. Cook the Spaghetti
Boil spaghetti in salted water for 2 minutes less than package directions (it’ll finish cooking in the oven). Drain and set aside.
2. Brown the Beef & Aromatics
In a large pot or Dutch oven, cook ground beef over medium-high heat until browned (6–8 minutes). Drain excess fat.
Add onion and cook 3–4 minutes until soft. Stir in garlic and cook 30 seconds more.
3. Build the Creamy Sauce
Stir in marinara sauce, Italian seasoning, red pepper flakes, salt, and pepper. Simmer 5 minutes.
Reduce heat to low. Add cream cheese and sour cream. Stir until melted and smooth—do not boil (high heat can cause cream cheese to curdle).
4. Combine & Bake
Stir cooked spaghetti into the sauce until fully coated.
Pour into a greased 9x13-inch baking dish.
Top with mozzarella and Parmesan.
Bake at 375°F (190°C) for 20–25 minutes, until cheese is melted and bubbly.
Let rest 5–10 minutes before serving—this helps it set for cleaner slices.
Tips for Casserole Success
- Don’t overcook the pasta—underdone noodles absorb sauce in the oven.
- Use room-temperature cream cheese—cold = lumpy sauce.
- Make it ahead: Assemble (unbaked), cover, and refrigerate for up to 24 hours. Add 10 minutes to bake time.
- Boost flavor: Add 1 tsp Worcestershire sauce or a splash of red wine to the meat.
- Freezer-friendly: Freeze unbaked casserole for up to 3 months. Thaw overnight, then bake as directed.
Delicious Variations
- Vegetarian: Swap beef for lentils, mushrooms, or plant-based crumbles
- Spicy Arrabbiata: Double the red pepper flakes + add roasted red peppers
- Cheesy Herb: Stir 2 tbsp fresh basil or oregano into the sauce
- Low-Carb: Use zucchini noodles or lupini pasta (add after baking)
- Italian Sausage: Use sweet or hot Italian sausage for deeper flavor
Serving Suggestions
- Classic comfort: With garlic bread and a simple green salad
- Kid-friendly: Serve with buttered peas or corn
- Date night: Pair with a glass of Chianti and crusty bread
- Potluck star: Transport in the baking dish—garnish with parsley before serving
Frequently Asked Questions (FAQs)
Q: Can I use cottage cheese instead of cream cheese?
A: Yes! Blend 1 cup cottage cheese until smooth for a lighter, ricotta-like texture.
Q: Why did my sauce curdle?
A: Likely from high heat or cold cream cheese. Melt cream cheese over low heat and use room-temperature dairy.
Q: Can I make this gluten-free?
A: Absolutely! Use GF spaghetti (like Barilla or Jovial) and ensure marinara is GF.
Q: Can I add vegetables?
A: Yes! Stir in 1 cup spinach, diced zucchini, or bell peppers with the sauce.
