Ingredients

• 1 lb spaghetti
• 1 lb lean ground beef
• 1 small onion, diced
• 2 cloves garlic, minced
• 1 (24 oz) jar marinara sauce
• 8 oz cream cheese, softened
• 1 cup cottage cheese
• ¼ cup sour cream
• 2 cups shredded mozzarella cheese
• 2 Tbsp butter, sliced

Instructions

1. Preheat oven to 350°F and grease a 9x13-inch baking dish.
2. Cook the spaghetti according to the package directions until al dente. Drain.
3. While the pasta cooks, brown the ground beef and onion in a large skillet. Drain any grease, then stir in the garlic, marinara sauce, Italian seasoning, garlic powder, onion powder, salt, and pepper. Simmer for 5 minutes.
4. In a bowl, mix together the cream cheese, cottage cheese, and sour cream until smooth.
5. Spread half of the spaghetti into the prepared baking dish. Top with half of the butter slices, then spread the cream cheese mixture evenly over the noodles.

8. Bake uncovered for 30–35 minutes, until hot and bubbly. Let rest for 10 minutes before serving.

Recipe Tips

• Let the casserole rest before cutting so it holds together better.
• Freshly shredded mozzarella melts more smoothly than pre-shredded cheese.
• Cottage cheese creates a creamy texture without making the casserole heavy.

Easy Variations

• Add sautéed mushrooms or bell peppers to the meat sauce.
• Swap ground beef for Italian sausage.
• Stir spinach into the sauce for extra vegetables.
• Top with grated Parmesan before serving.

Make-Ahead Instructions

Assemble the casserole up to one day ahead. Cover and refrigerate until ready to bake.

You may need to add 5–10 extra minutes to the baking time if baking directly from the refrigerator.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days.

Freeze the baked or unbaked casserole for up to 3 months.

Frequently Asked Questions

Can I use ricotta instead of cottage cheese?

Yes! Ricotta works well, but cottage cheese is often more budget-friendly and creates a similar creamy texture.

Can I freeze this casserole?

Absolutely. Assemble it before baking or freeze leftovers in individual portions for easy meals later.

Can I use a different pasta?

Yes. Penne or rotini work well, though traditional spaghetti gives this dish its classic look.
