What Ingredients You Will Need

This Crockpot Million Dollar Spaghetti recipe sticks to simple, everyday ingredients that come together for big, bold flavor. You can find everything at a standard grocery store—and probably already have half of it in your kitchen.

• For the Pasta:
  • 16 oz (450 g) spaghetti noodles (regular or whole wheat; gluten-free works too, just cook al dente)
• For the Meat Sauce:
  • 1 lb (450 g) ground beef (I use 85% lean for flavor, but turkey or sausage works too)
  • 1 small onion, diced (yellow or white; adds sweetness and depth)
  • 4 cloves garlic, minced (fresh is best, but pre-minced works in a pinch)
  • 1 jar (24 oz/680 g) marinara sauce (Rao’s is my go-to for rich flavor, but any favorite works)
  • 1 can (14.5 oz/410 g) diced tomatoes, drained (adds texture and brightness)
  • 1 tsp dried Italian seasoning (oregano, basil, thyme blend; or just Italian seasoning mix)
  • Salt and pepper, to taste
• For the Creamy Cheese Layer:
  • 8 oz (225 g) cream cheese, softened (full-fat or reduced-fat both work)
  • 1 cup (240 g) cottage cheese (small curd; adds creaminess and protein)
  • 1 cup (250 g) sour cream (for a tangy, rich filling; Greek yogurt is a good sub)
• For the Cheesy Topping:
  • 3 cups (340 g) shredded mozzarella cheese (whole milk melts best)
  • 1/2 cup (50 g) grated parmesan cheese (freshly grated if you can—it’s worth it!)
• Optional Add-ins & Substitutions:
  • Chopped spinach or kale (for a veggie boost; stir into cheese layer)
  • Red pepper flakes (for a little kick)
  • Gluten-free spaghetti (sub for regular if needed)
  • Ground turkey or Italian sausage (swap for beef, or do half-and-half)

Ingredient Tips: I usually grab store-brand spaghetti and cottage cheese, but I splurge on good marinara like Rao’s or Classico for maximum flavor. For the cheese, grating your own mozzarella makes a difference, but pre-shredded is totally fine when you’re busy. If you want a richer flavor, try half mozzarella and half provolone for the topping. And honestly, don’t skip the cottage cheese—it makes the filling extra creamy and helps bind everything together.

Equipment Needed

• Crockpot (Slow Cooker): A 6-quart model is perfect for this recipe. If you only have a smaller one, just halve the ingredients. I use my basic Hamilton Beach crockpot and it’s survived years of spaghetti duty.
• Large Skillet or Sauté Pan: For browning the ground meat and sautéing onions and garlic. Nonstick or cast iron both work—use what you love.
• Large Pot: For boiling the spaghetti. No need for a fancy pasta pot, just a basic stockpot will do.
• Colander: For draining the pasta. I have a collapsible silicone one that saves space.
• Mixing Bowls: You’ll want a medium bowl for the cheesy filling and a big one for the meat sauce (if you like to mix everything before layering).
• Wooden Spoon or Spatula: For stirring up the cheesy layer and meat sauce.
• Measuring Cups & Spoons: For getting those cheese ratios just right.
• Cooking Spray or Olive Oil: To grease the crockpot insert—trust me, it helps with cleanup.

Equipment Notes: If you don’t own a crockpot, you can bake this in a big casserole dish at 350°F (175°C) for about 40 minutes, covered with foil. I’ve even made it in my Instant Pot on the slow cook setting. And for cleanup, soak your crockpot insert overnight with warm soapy water—it makes a world of difference!

How to Make Crockpot Million Dollar Spaghetti

1. Prep Your Slow Cooker: Spray the crockpot insert generously with cooking spray or brush with a little olive oil. This keeps the cheesy edges from sticking and makes serving (and cleaning) so much easier.
2. Boil the Pasta: Bring a large pot of salted water to a boil. Add 16 oz (450 g) spaghetti noodles and cook for 7-8 minutes, until just shy of al dente. You want the noodles a bit firm since they’ll cook more in the crockpot. Drain and set aside. (Don’t overcook, or you’ll get mushy spaghetti!)
3. Make the Meat Sauce: In a large skillet, brown 1 lb (450 g) ground beef over medium-high heat, breaking it up as it cooks (about 5-7 minutes). Add diced onion and cook until translucent, about 3 minutes. Stir in minced garlic and cook another 1 minute until fragrant. Drain excess fat if needed. Pour in the 24 oz (680 g) jar of marinara, drained diced tomatoes, and Italian seasoning. Season with salt and pepper. Let it simmer for 5 minutes to meld the flavors.
4. Mix the Creamy Cheese Layer: In a medium bowl, combine 8 oz (225 g) cream cheese, 1 cup (240 g) cottage cheese, and 1 cup (250 g) sour cream. Beat with a wooden spoon or hand mixer until smooth and fluffy. (Tip: let the cream cheese soften to room temp for easier mixing!)
5. Layer in the Crockpot:
   • Spoon about 1 cup (240 ml) of the meat sauce into the bottom of the crockpot—just enough to cover.
   • Add half of the cooked spaghetti, spreading it evenly.
   • Dollop half the cheese mixture over the noodles and gently spread it out.
   • Sprinkle with 1 cup mozzarella and a little parmesan.
   • Repeat layers: meat sauce, remaining spaghetti, remaining cheese mixture, and another cup mozzarella and parmesan.
   • Pour final layer of meat sauce on top and finish with the rest of the mozzarella and parmesan.
6. Cook: Cover and cook on LOW for 3-4 hours or HIGH for 2 hours. It’s ready when the cheese is melted and bubbly around the edges. (If your crockpot runs hot, check at 2.5 hours on low.)
7. Serve: Let it rest for 15-20 minutes with the lid off before serving. This helps the layers set so it scoops up beautifully. Garnish with chopped fresh parsley if you’re feeling fancy!

Troubleshooting: If the spaghetti seems watery, let it cook uncovered for 20 minutes before serving. If the cheese browns too quickly, switch to “keep warm” and cover loosely with foil. If you’re prepping ahead, assemble everything in the insert and store in the fridge overnight.

Cooking Tips & Techniques

• Don’t overcook the pasta: Always undercook your spaghetti by a minute or two. It finishes cooking in the crockpot and keeps its bite (no mushy noodles!).
• Layering is key: Start and finish with sauce and cheese on top. This keeps the noodles moist and gives you those irresistible golden, cheesy edges.
• Let the cream cheese soften: Trust me, cold cream cheese is a nightmare to mix. Leave it out while you prep the sauce and it’ll blend up smooth and luscious.
• Use quality marinara: Since this dish is all about layers, a flavorful sauce really shines. If you have homemade, go for it! Otherwise, pick a store-bought one with rich tomato flavor.
• Got a runny sauce? Simmer it a few extra minutes before layering—or add a tablespoon of tomato paste for thickness. I made this mistake more than once, and thickening the sauce first totally solved it.
• Make ahead and reheat: Million dollar spaghetti is even better the next day. Store leftovers in the crockpot or an airtight container, then reheat gently in the microwave or oven.
• Keep it from sticking: Always spray your crockpot insert! I’ve forgotten before and learned my lesson scraping out stuck cheese for days after.
• Customize the cheese: If you love a cheesier top, sprinkle on extra mozzarella in the last 30 minutes of cooking for a gooey finish.

Honestly, my biggest “oops” was overcooking the noodles the first time. I also once forgot to drain the tomatoes—let’s just say, you don’t want watery spaghetti soup! But with a little practice, you’ll get beautiful, sliceable layers every time. It’s basically foolproof once you get the hang of the layering and timing.

Variations & Adaptations

• Vegetarian: Skip the ground beef and use sautéed mushrooms, zucchini, and spinach for a hearty veggie version. You can also use a plant-based ground “meat” substitute.
• Low-Carb/Keto: Swap out regular spaghetti for spiralized zucchini (“zoodles”) or hearts of palm noodles. You may need to reduce the cook time slightly to prevent sogginess.
• Spicy Italian: Use hot Italian sausage instead of ground beef and stir red pepper flakes into the sauce. Top with sliced pepperoncini for extra zing.
• Allergy-Friendly: For gluten-free, use a certified GF pasta and double-check your sauce. To make it nut-free, avoid nut-based cheeses or toppings.
• Different cheeses: Swap mozzarella for provolone, fontina, or even pepper jack for a twist. I once added smoked gouda and it gave the whole dish a fun, bold flavor.
• Make it extra veggie-packed: Add layers of roasted eggplant or thin-sliced bell peppers between the noodles and cheese. Even picky eaters hardly notice!

One of my favorite tweaks is stirring in a cup of chopped baby spinach into the cheese mixture before layering. It wilts into the filling and adds a pop of green (and nutrition) without anyone noticing. You can absolutely make this recipe your own—just stick to the basic layering and proportions for best results.

Serving & Storage Suggestions

This Crockpot Million Dollar Spaghetti is best served hot, straight from the crockpot. I love to scoop out generous portions with a big spoon, making sure every serving gets some of that golden cheese from the top. Sprinkle with chopped parsley or fresh basil for a pretty finishing touch.

• Serving ideas: Pair with a crisp green salad and warm garlic bread for the ultimate comfort dinner. If you want to get fancy, serve with a side of roasted broccoli or a glass of red wine.
• Storage: Leftovers keep well in an airtight container in the fridge for up to 4 days. The flavors actually meld and improve overnight!
• Freezer tips: You can freeze the fully cooked spaghetti in portions. Wrap tightly with foil and transfer to freezer bags. Thaw overnight in the fridge before reheating for best texture.
• Reheating: Reheat in the microwave (covered, in 1-2 minute bursts) or in a 325°F (160°C) oven, covered with foil, until hot and bubbly. Add a splash of extra marinara if it seems a bit dry.

Honestly, this dish is so forgiving. If you’re hosting a party, keep it on “warm” in the crockpot for up to two hours and guests can serve themselves. And if you have leftovers (rare in my house!), they make the coziest next-day lunch ever.

Nutritional Information & Benefits

This recipe makes about 8 generous servings. Each serving contains approximately:

• Calories: 540
• Protein: 28g
• Fat: 26g
• Carbs: 47g
• Fiber: 3g

Health perks: Thanks to the cottage cheese and ground beef, this dish is higher in protein than standard spaghetti. You get calcium from the mozzarella and a hearty helping of lycopene (an antioxidant) from the tomato sauce. Swap in whole wheat or gluten-free pasta for extra fiber or special dietary needs.

This recipe does contain dairy and gluten, so be mindful if you have allergies or sensitivities. Personally, I love that it packs in so much flavor and comfort, but still offers a good balance of macronutrients—especially if you add veggies or swap in lean ground turkey. It’s not “light” food, but it’s real, satisfying, and hits the spot every time.
