What you’ll need

Here’s everything you’ll need to make this comforting baked spaghetti dish:

Main ingredients

• Ground beef (1 pound) – This forms the hearty base of the dish. I like using lean ground beef so it’s not too greasy.
• Onion (1 large, chopped) – Adds sweetness and depth to the sauce.
• Green pepper (1 medium, chopped) – Brings a fresh, slightly crisp texture and mild bitterness that balances the richness.
• Diced tomatoes (14.5 oz can, undrained) – Provides the tangy, juicy base for the sauce.
• Water (1 cup) – Helps loosen the sauce and allows all the flavors to meld together.
• Chili powder (2 tablespoons) – Adds a warm, slightly smoky flavor that makes this dish unique.
• Frozen corn (10 oz, thawed) – Adds sweetness and texture.
• Frozen peas (10 oz, thawed) – Brings a pop of color and gentle sweetness.
• Mushroom stems and pieces (4 oz can, drained) – Adds an earthy, savory note.
• Salt and pepper (to taste) – Essential for seasoning.
• Spaghetti (12 oz, cooked and drained) – The foundation of the dish.
• Cheddar cheese (2 cups, shredded and divided) – Melty, cheesy goodness on top and throughout.

Tools for this recipe

You don’t need anything fancy to make this recipe, which is another reason it’s such a classic:

• Large skillet or sauté pan
• Big pot for boiling spaghetti
• 9×13-inch baking dish
• Wooden spoon or spatula
• Colander for draining pasta

I usually make the sauce in a deep skillet and then combine everything right in a large mixing bowl before transferring it to the baking dish.

How to make Church Supper Spaghetti

This is a simple overview with step-by-step guidance. Full instructions are in the recipe card below.

Step 1: Cook the spaghetti

Bring a large pot of salted water to a boil and cook the spaghetti according to package instructions. Drain and set aside.

Step 2: Brown the beef and veggies

In a large skillet over medium-high heat, cook the ground beef, chopped onion, and green pepper together. Cook until the beef is browned and the vegetables are softened. Drain any excess fat if needed.

Step 3: Build the sauce

Stir in the diced tomatoes (with juices), water, chili powder, corn, peas, and mushrooms. Mix everything well and let it simmer for about 10–15 minutes so the flavors can develop.

Step 4: Combine with spaghetti

Add the cooked spaghetti to the sauce and toss everything together until evenly coated. Season with salt and pepper to taste.

Step 5: Assemble the casserole

Transfer the mixture into a greased 9×13-inch baking dish. Sprinkle 1 ½ cups of cheddar cheese evenly over the top.

Step 6: Bake

Bake in a preheated oven at 350°F (175°C) for about 20–25 minutes, or until the cheese is melted and bubbly.

Step 7: Finish and serve

Remove from the oven and sprinkle the remaining cheese on top if desired. Let it rest for a few minutes before serving.

Pro tips

• Don’t overcook the pasta – Slightly undercook it since it will continue cooking in the oven.
• Drain excess grease – This keeps the dish from becoming too oily.
• Let it rest before serving – Helps everything set and makes it easier to slice and serve.
• Use freshly shredded cheese – It melts better and tastes richer than pre-shredded.

Substitutions and variations

This recipe is super flexible, which makes it even more useful:

• Swap ground beef – Try ground turkey or chicken for a lighter version.
• Make it spicy – Add red pepper flakes or a dash of hot sauce.
• Add more veggies – Zucchini, carrots, or spinach work well.
• Use different cheese – Mozzarella or a cheddar blend can be used for a different flavor.
• Make it creamy – Stir in a bit of cream cheese or sour cream for a richer texture.

What to serve with Church Supper Spaghetti

This is a hearty dish, so you don’t need much on the side:

• Garlic bread or dinner rolls
• Simple green salad
• Coleslaw
• Roasted vegetables

I personally love serving it with warm, buttery bread to soak up all that delicious sauce.

Leftovers and storage

• Fridge: Store leftovers in an airtight container for up to 3–4 days.
• Reheating: Warm in the oven or microwave until heated through. Add a splash of water if it seems dry.
• Freezing: This dish freezes well! Store in a freezer-safe container for up to 2 months. Thaw overnight before reheating.

This dish truly lives up to its name. It’s exactly the kind of meal you’d find at a church supper—simple, generous, and made with love. It feeds a crowd, travels well, and tastes just as good (if not better) the next day.
