Ingredients You’ll Need

The magic of this Beef Mushroom Johnny Marzetti Casserole Recipe lies in the fresh and accessible ingredients. They complement each other beautifully—the earthiness of mushrooms plays off the savory beef, and the cheese brings everything together. When shopping, I like to pick fresh, firm mushrooms and good-quality cheddar to really make the flavors shine.

• Mushrooms: I recommend cremini or white button mushrooms—they have a great texture and absorb flavors well.
• Olive oil or neutral cooking oil: Olive oil adds a lovely depth, but a neutral oil works if you want a cleaner taste.
• Onion: Yellow or white onions both work; they provide that sweet, aromatic foundation.
• Garlic: Freshly minced garlic brings that punch that your family will notice, trust me.
• Bell pepper: Any color you like—red adds sweetness, green gives a sharper bite.
• Salt: Essential for bringing out all the flavor, so don’t skimp here.
• Lean ground beef: I use 90:10 lean-to-fat ratio—it’s juicy but not greasy.
• Whole plum tomatoes in juice: Crushing them by hand is key for chunky, flavorful sauce.
• Tomato paste: Packs a concentrated tomato punch for body and color.
• Dried oregano: Adds a subtle, earthy herbiness that complements the sauce.
• Crushed red pepper flakes: Just a pinch to give a gentle kick.
• Freshly ground black pepper: I always add fresh for maximum flavor.
• Uncooked elbow macaroni: Classic pasta choice for that nostalgic texture.
• Grated cheddar cheese: The gooey, melty topping that makes everyone smile.
• Grated Parmesan cheese: Adds a nice sharpness and depth layered with the cheddar.

Variations

I always encourage tweaking a recipe to suit your tastes or dietary needs. This Beef Mushroom Johnny Marzetti Casserole Recipe is perfect for experimenting—whether you want to go lighter, add veggies, or spice it up, there’s room for your own personal touch.

• Vegetarian Version: Swap the ground beef for a meatless ground substitute or extra mushrooms, and skip this one when I tried it—it was surprisingly satisfying!
• Cheese Variety: Mixing mozzarella or Monterey Jack with cheddar gives a milder, stretchier melt.
• Extra Veggies: Adding zucchini or chopped spinach sneaks in freshness without changing the homey vibe.
• Mild Heat: Adjust crushed red pepper flakes to taste, or try a dash of smoked paprika for a smoky twist.

How to Make Beef Mushroom Johnny Marzetti Casserole Recipe

Step 1: Sauté Mushrooms to Perfection

Start by heating a dry skillet over medium-high heat and add your chopped or sliced mushrooms. You’ll notice they’ll release their moisture quickly—stir occasionally as they soften and brown slightly, about 5 to 8 minutes. This step is key for that rich, concentrated mushroom flavor and to avoid watery sauce later. Once done, scoop them out into a bowl and wipe your skillet clean.

Step 2: Build the Flavor Base

Add your oil to the cleaned skillet, then toss in onions and cook until translucent—about 6 minutes. You’ll love how the kitchen fills with that sweet aroma! Next, add garlic and bell pepper, cooking for another minute to mellow their flavors. Don’t forget to salt generously here to soften the veggies and bring out their natural sweetness.

Step 3: Brown the Beef

Turn your heat to medium and add the ground beef. Break it up into small pieces with your spoon while cooking until it loses the pink color—about 8 minutes. I find patience here pays off; properly browned beef gives the sauce a deep, robust flavor.

Step 4: Create the Tomato Sauce

This part’s a little messy but so worth it—wear an apron! Use your hands to crush the canned whole plum tomatoes directly in the pan, including all the juice. Then stir in tomato paste, oregano, red pepper flakes, and black pepper. Let everything simmer gently for around 20 minutes until the sauce thickens. Toss in the reserved mushrooms and simmer for another 2 minutes. This slow cooking melds all the flavors into something simple but extraordinary. Always taste at the end and adjust salt if needed.

Step 5: Cook Pasta & Combine

While the sauce simmers, boil salted water and cook the elbow macaroni until it still has a slight bite—al dente works best because it’ll bake more in the oven. Drain, then return the pasta to the pot and mix in the sauce thoroughly. Stir in half of the cheddar and Parmesan cheeses to get a smooth, cheesy base before transferring everything to your prepared baking dish.

Step 6: Bake to Gooey Golden Perfection

Spread your mixture evenly in the dish, then sprinkle the remaining cheeses on top. Bake uncovered at 350°F (175°C) for about 30 minutes until you see the sauce bubbling and the cheese has turned a gorgeous golden brown. Let it rest for 10 minutes before serving—this info came from experience; you don’t want molten cheese surprise in every bite!

How to Serve Beef Mushroom Johnny Marzetti Casserole Recipe

Garnishes

I like to freshen this casserole up with a sprinkle of chopped fresh parsley or basil right before serving. The green pop of color brightens the rich flavors and adds a fresh, herby note that cuts through the cheese and beef wonderfully.

Side Dishes

This casserole is a meal on its own, but I often pair it with simple sides like a crisp green salad, steamed green beans, or roasted broccoli for a nice contrast in texture and a touch of brightness.

Creative Ways to Present

For a fun twist during holidays or family gatherings, I’ve plated individual portions in small ramekins—baked until bubbly and served directly to the table. It’s a fun way to impress guests and makes portion control a breeze.

Make Ahead and Storage

Storing Leftovers

I tightly cover leftovers with foil or plastic wrap and refrigerate them for up to 4 days. This casserole reheats beautifully, and it actually tastes even better the next day once the flavors have had time to mingle.

Freezing

I’ve frozen the whole assembled casserole before baking, wrapped tightly in foil and freezer-safe plastic wrap. When I’m ready to eat, I let it thaw overnight in the fridge and then bake as usual. The texture and flavor hold up surprisingly well, making it perfect for busy weeks.

Reheating

To reheat, I cover leftovers loosely with foil and warm them in a 350°F oven until heated through, about 20 minutes. This keeps the cheese gooey without drying out the pasta, something microwave reheats can sometimes overcook.
