What is Johnny Marzetti Casserole?

The Johnny Marzetti casserole is a baked pasta dish layered with savory ground beef, sautéed vegetables, tangy tomato sauce, and plenty of gooey cheese. It’s the ultimate one-dish meal — a hybrid between a baked ziti and a lasagna, but with a Midwestern twist. Traditionally made with elbow macaroni, cheddar cheese, ground beef, and tomato sauce, it’s simple, comforting, and utterly satisfying.

This dish has Midwestern roots, particularly in Ohio, where it became a staple in home kitchens and school cafeterias. But the legend of Johnny Marzetti stretches back even further — all the way to a restaurant in Columbus, Ohio, called Marzetti’s.

A Brief History of Johnny Marzetti

Back in the early 20th century, Teresa Marzetti, an Italian immigrant, opened an Italian restaurant in Columbus, Ohio. She named one of her hearty baked pasta dishes after her brother-in-law, Johnny. And just like that, the Johnny Marzetti casserole was born — and the rest is delicious history.

Over the decades, this dish became a sensation throughout the Midwest, especially in school cafeterias, church potlucks, and family reunions. It’s the kind of recipe that brings generations together at the dinner table. No one ever asks “what’s for dinner?” twice when Johnny Marzetti is in the oven.

Why Johnny Marzetti Still Matters Today

Let’s be real: comfort food never goes out of style. In an age of trendy diets and complicated recipes, there’s something deeply reassuring about a Johnny Marzetti casserole. It’s rich, easy to prepare, customizable, and feeds a crowd. Whether you’re cooking for your family, meal prepping for the week, or hosting a casual gathering, this casserole checks every box.

Plus, it’s an excellent way to stretch a pound or two of ground beef into a meal that feels like a feast. And don’t even get us started on the leftovers — somehow, it tastes even better the next day.

Ingredients Breakdown: Why Each One Matters

Let’s take a closer look at the ingredients in this Johnny Marzetti casserole and why they work together to create such mouthwatering magic.

1. Mushrooms (12 oz)

Mushrooms add umami, a deep savory flavor that enhances the richness of the beef. Browning them first draws out moisture and intensifies their taste, making your casserole that much more flavorful.

2. Olive Oil (1 tablespoon)

A healthy fat that brings out the flavor in vegetables and helps everything cook evenly. You can use a neutral oil, but a light olive oil adds a hint of complexity.

3. Onion (1 large, chopped)

The base of any good savory dish. Onions add sweetness and depth once softened and slightly caramelized.

4. Garlic (5 cloves, minced)

Because what’s a comfort food without garlic? It adds a fragrant bite that blends beautifully with tomato and beef.

5. Bell Pepper (1, any color)

For a touch of sweetness and crunch. Red peppers are most common, but yellow or orange work just as well.

6. Salt & Pepper (to taste)

Never underestimate the power of seasoning! These basic ingredients are key to unlocking bold, satisfying flavors.

7. Lean Ground Beef (1½ pounds, 90:10)

The star of the show! Ground beef adds richness, protein, and that crave-worthy, meaty bite.

8. Whole Plum Tomatoes in Juice (28 oz can)

These tomatoes offer a more vibrant flavor than crushed or diced. Crush them by hand or with a spoon as they simmer into the sauce.

9. Tomato Paste (3 tablespoons)

Tomato paste deepens the tomato flavor and adds thickness to your sauce.

10. Dried Oregano (¾ teaspoon)

Classic Italian seasoning. A little goes a long way in evoking that old-school Italian flavor profile.

11. Crushed Red Pepper Flakes (¼ teaspoon)

For a subtle kick. You can always dial this up or down based on your spice preference.

12. Elbow Macaroni (12 oz)

Short pasta that holds onto sauce and cheese perfectly. Al dente is the goal here so it doesn’t turn mushy in the oven.

13. Cheddar Cheese (8 oz, grated)

Sharp and melty, cheddar cheese gives this casserole its signature gooey top.

14. Parmesan Cheese (4 oz, grated)

Salty and nutty, Parmesan adds complexity and that golden-brown crust we all love.

How to Make the Perfect Johnny Marzetti Casserole (Step-by-Step)

Let’s walk through each stage of preparing your Johnny Marzetti casserole so you can get it right the first time and every time after that.

1. Preheat and Prep

Start by setting your oven to 350°F. Grease a 9×13-inch baking dish with cooking spray or a bit of oil and set it aside.

2. Cook the Mushrooms

Use a large, deep skillet. Dry sauté the mushrooms (no oil yet!) over medium-high heat. Stir occasionally until they’ve browned and released most of their moisture — around 5 to 8 minutes. Transfer to a bowl and set aside.

3. Sauté the Aromatics

In the same skillet, heat 1 tablespoon of olive oil. Add onions, garlic, and chopped bell pepper. Season with a pinch of salt. Cook until softened and fragrant — about 5 minutes.

4. Brown the Beef

Add the ground beef to your skillet. Break it up as it cooks. Once it’s browned and cooked through, drain off any excess fat.

5. Build the Sauce

Now stir in the canned tomatoes with their juice (break them up with a spoon), tomato paste, oregano, red pepper flakes, salt, and black pepper. Simmer for 10 minutes to let the flavors marry.

6. Boil the Pasta

Bring a large pot of salted water to a boil. Cook elbow macaroni until just al dente — about 1 minute less than package instructions. Drain and set aside.

7. Combine Everything

In a large bowl, mix the cooked pasta, beef sauce, and mushrooms. Fold in half the grated cheddar and half the Parmesan.

8. Assemble

Pour the mixture into your prepared baking dish. Spread evenly and top with the remaining cheeses.

9. Bake

Place in the oven and bake uncovered for about 30 minutes, or until the cheese is bubbly and golden.

10. Rest & Serve

Let it sit for 5–10 minutes after baking. This allows everything to set up, making for neater slices and more intense flavor.

Tips & Tricks for Johnny Marzetti Mastery

To elevate your Johnny Marzetti casserole from good to unforgettable, try these tips:

Don’t overcook the pasta – It’ll continue cooking in the oven. Al dente is your friend.

Mix meats – Swap in Italian sausage for half the beef for a flavor boost.
Add veggies – Zucchini, spinach, or even shredded carrots can sneak in some nutrition.
Double it – Make two and freeze one. It’s an ideal freezer meal!
