Ingredients List

For the Meat Sauce:

· 1 lb (450g) lean ground beef (85/15 recommended)
· 1 small yellow onion, finely diced
· 3 cloves garlic, minced
· 1 teaspoon kosher salt
· ½ teaspoon black pepper
· 1 teaspoon dried Italian seasoning
· 1 jar (24 oz) marinara sauce or your favorite pasta sauce
· ½ cup water (swirl in the jar to capture leftover sauce)

For the Pasta:

· 12 oz (about 3 ½ cups) dry pasta (penne, ziti, rigatoni, or mostaccioli)

For the Cheesy Layer:

· 15 oz (about 1 ¾ cups) whole-milk ricotta cheese
· 1 large egg, lightly beaten
· ½ cup grated Parmesan cheese, divided
· 2 cups shredded mozzarella cheese, divided
· 2 tablespoons fresh parsley, chopped (optional)

Step-by-Step Instructions

Step 1: Preheat and Prepare

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with non-stick spray.

Step 2: Cook the Pasta

Bring a large pot of salted water to a boil. Cook the pasta according to package directions until al dente (about 1 minute less than the package recommends, as it will continue cooking in the oven). Drain well and set aside.

Step 3: Brown the Ground Beef

While the pasta cooks, heat a large skillet over medium-high heat. Add the ground beef and cook for 5-6 minutes, breaking it up with a spoon, until browned and no longer pink. Add the diced onion and cook for 3 minutes until softened. Add the minced garlic and cook for 60 seconds until fragrant. Drain any excess fat.

Step 4: Make the Meat Sauce

Reduce the heat to low. Add the salt, pepper, Italian seasoning, marinara sauce, and water to the skillet. Stir to combine. Simmer for 5 minutes to let the flavors meld.

Step 5: Make the Ricotta Mixture

In a small bowl, combine the ricotta cheese, beaten egg, ¼ cup of the Parmesan cheese, and parsley (if using). Mix until smooth.

Step 6: Assemble the Casserole

Spread about 1 cup of the meat sauce on the bottom of the prepared baking dish. Add half of the cooked pasta in an even layer. Top with half of the remaining meat sauce. Drop spoonfuls of the ricotta mixture over the sauce and spread gently. Sprinkle with 1 cup of the mozzarella cheese. Repeat the layers: remaining pasta, remaining meat sauce, remaining ricotta mixture, and remaining 1 cup of mozzarella. Sprinkle the remaining ¼ cup of Parmesan cheese over the top.

Step 7: Bake

Cover the baking dish with foil. Bake for 20 minutes. Remove the foil and bake for another 10-15 minutes, until the casserole is hot and bubbly and the cheese is melted and lightly golden.

Step 8: Rest and Serve

Remove from the oven and let the casserole rest for 10 minutes. This allows the layers to set, making it easier to cut and serve. Garnish with additional parsley if desired.

Cooking Tips and Pro Tips for Best Results

· Do not overcook the pasta: Cook the pasta until al dente (firm to the bite). It will continue cooking and absorb liquid in the oven. Overcooked pasta becomes mushy.
· Use whole-milk ricotta: Low-fat or non-fat ricotta can become watery and grainy during baking. Whole-milk ricotta creates a creamy, rich layer.
· Use freshly shredded cheese: Pre-shredded cheese contains anti-caking agents that prevent smooth melting. Shredding from a block yields a creamier, more cohesive topping.
· Let the casserole rest: Resting for 10 minutes allows the layers to set. Cutting too soon will result in a soupy, messy casserole.
· Make it ahead: Assemble the casserole completely but do not bake. Cover and refrigerate for up to 24 hours. Add 10-15 minutes to the baking time (cover with foil for the first 20 minutes).

Variations and Substitutions

Spicy Cheesy Ground Beef Casserole:
Use hot Italian sausage instead of ground beef (or mix ½ lb beef with ½ lb sausage). Add ½ teaspoon of crushed red pepper flakes to the meat sauce. Use pepper jack cheese instead of mozzarella.

Vegetable-Packed Casserole:
Add 1 cup of finely chopped mushrooms, 1 cup of diced zucchini, or 1 cup of frozen spinach (thawed and squeezed dry) to the meat sauce. Sauté the vegetables with the onion.

Cheesy Ground Beef and Rice Casserole:
Substitute the pasta with 1 ½ cups of uncooked long-grain white rice. Increase the water to 1 ½ cups. Cover and bake for 40-45 minutes, until the rice is tender.

Low-Carb / Keto Casserole:
Substitute the pasta with 2 cups of cauliflower florets (chopped small) or 2 cups of zucchini noodles (squeezed dry). Reduce the baking time to 15-20 minutes.

Gluten-Free Cheesy Casserole:
Use gluten-free pasta (brown rice or chickpea-based). Ensure your marinara sauce is gluten-free. The rest of the ingredients are naturally gluten-free.

Greek-Inspired Casserole:
Add ½ teaspoon of dried oregano and ¼ teaspoon of cinnamon to the meat sauce. Use crumbled feta cheese (½ cup) along with the mozzarella. Serve with a dollop of tzatziki.

Serving Suggestions

This cheesy baked ground beef casserole is a complete meal. Serve it with:

Frequently Asked Questions (FAQ)

1. Can I use a different type of pasta?
Yes. Penne, ziti, rigatoni, mostaccioli, fusilli, or shells all work beautifully. Adjust the amount to about 12 oz (3-4 cups). Do not use long noodles like spaghetti, which can clump together.

2. Can I use cottage cheese instead of ricotta?
Yes. Substitute the ricotta with 1 ½ cups of full-fat cottage cheese (drained). Blend it in a food processor for a few seconds to smooth out the texture, or use it as is for a chunkier filling.

3. Why is my casserole watery?
A watery casserole usually comes from using low-fat ricotta, not draining the pasta well, or adding too much sauce. Use whole-milk ricotta. Drain the pasta thoroughly. Do not add extra water beyond the ½ cup used to rinse the jar.

4. Can I make this casserole in a slow cooker?
Yes. Brown the beef and sauté the vegetables on the stovetop first. Layer the ingredients in a slow cooker (pasta, sauce, ricotta, cheese). Cook on low for 3-4 hours or on high for 2-3 hours. The texture will be softer than the baked version.

5. Can I add mushrooms or other vegetables to this casserole?
Absolutely. Sauté 8 oz of sliced mushrooms with the onion. Add 1 cup of frozen peas or chopped spinach (thawed and squeezed dry) to the meat sauce. Do not add more than 2 cups of extra vegetables, or the casserole may become watery.

6. Can I double this recipe for a larger crowd?
Yes. Use a 9×13-inch dish for a single batch. For a double batch, use a large roasting pan (10×15 or larger) or two 9×13 dishes. The baking time may increase by 5-10 minutes. Check that the center is hot and bubbly.
