Check out the full guide below to see how easy dinner can be.

The Secret to a Faster Lasagna

The biggest problem with lasagna is the noodles. They are long and slippery. If you boil them, they often stick together in the pot. If you use the no-boil kind, they can sometimes stay crunchy or dry. I found a way to skip all that trouble. Instead of flat noodles, I use frozen cheese ravioli. Think about it for a second. A cheese ravioli is just a tiny pocket of pasta filled with ricotta cheese. That is exactly what you find inside a layer of lasagna! By using ravioli, you get the pasta and the cheese filling in one simple step.

I first tried this when I was in a huge rush for a potluck. I had a bag of frozen ravioli in my freezer and a jar of sauce. I layered them up and hoped for the best. To my surprise, everyone loved it more than my regular lasagna. It was thick, hearty, and very easy to scoop. Now, I rarely make it the old way. This version is just more fun to eat. It is also very hard to mess up. Even if you are not a great cook, you can handle this dish. It is basically just stacking ingredients in a pan and letting the oven do the hard work.

What You Will Need to Buy

Before you start, you need to gather your supplies. You can find everything at any local grocery store. I like to keep these items in my freezer and pantry so I can make this on a whim. For this recipe, you need one large bag of frozen cheese ravioli. Usually, a 25-ounce bag is just right for a 9 by 13 inch baking pan. Do not thaw them out first. Using them straight from the freezer actually helps the casserole hold its shape while it bakes. It also keeps the pasta from getting too mushy.

You will also need meat, sauce, and extra cheese. I use one pound of ground beef, but you could use ground turkey or Italian sausage if you prefer. For the sauce, grab two jars of your favorite marinara. You want it to be saucy so the pasta cooks through. Finally, you need a big bag of shredded mozzarella cheese and some parmesan. I usually buy the pre-shredded kind to save even more time. Having everything ready on the counter makes the process go fast. You will be done with the prep in about ten minutes.

• 25 oz bag frozen cheese ravioli
• 1 lb ground beef or sausage
• 48 oz marinara sauce (two jars)
• 2 cups shredded mozzarella cheese
• 1/2 cup grated parmesan cheese
• 1 tsp dried oregano
• 1/2 tsp garlic powder

Step by Step Cooking Guide

First, you need to heat your oven to 400 degrees. While that is warming up, put your ground beef in a large skillet over medium heat. Cook it until it is brown and no longer pink. I always drain the fat out of the pan after cooking. If you leave the grease in, the lasagna will be too oily. Once the meat is ready, pour one jar of sauce right into the skillet with the meat. Add your garlic powder and oregano here too. Stir it all together until it is hot. This meat sauce is the base of your flavor.

Now comes the layering. Grab your baking dish and spread a little bit of plain sauce on the very bottom. This stops the pasta from sticking. Place half of your frozen ravioli in a single layer over the sauce. It is okay if they touch or overlap a little bit. Pour half of your meat sauce over the ravioli. Sprinkle on half of your mozzarella cheese. Repeat the layers one more time: the rest of the ravioli, the rest of the meat sauce, and the rest of the cheese. Top it off with the parmesan cheese for a salty crunch.

1. Brown the meat and drain the grease.
2. Mix meat with one jar of sauce and spices.
3. Spread a thin layer of plain sauce in a 9×13 pan.
4. Add a layer of frozen ravioli.
5. Top with meat sauce and mozzarella.
6. Repeat layers and finish with parmesan.
7. Cover with foil and bake for 30 minutes.
8. Uncover and bake for 15 more minutes until bubbly.

Tips for the Best Results

Even though this is a lazy recipe, there are a few tricks to make it taste like you spent all day on it. One mistake I made once was not using enough sauce. Since the ravioli is frozen and the pasta is dry, it needs moisture to soften up. If the edges look dry before you put it in the oven, add a splash of water or more sauce around the sides. Another tip is to cover the pan tightly with aluminum foil for the first half of baking. This traps the steam inside, which cooks the pasta perfectly. If you leave it uncovered the whole time, the cheese might burn before the middle is hot.

I also suggest letting the casserole sit for at least 10 minutes after you take it out of the oven. This is the hardest part because it smells so good! However, if you cut it right away, the sauce will run everywhere. Letting it rest helps the layers set so you get a nice, clean square on your plate. If you want a prettier look, sprinkle some fresh parsley on top right before serving. It adds a pop of green that makes the red sauce look even better. IMO, the resting time is what turns a good casserole into a great one.

Changing Up the Flavors

One thing I love about this dish is how easy it is to change. If you do not want beef, you can use ground chicken or even small pieces of pepperoni. For my friends who do not eat meat, I just skip the beef entirely. You can add extra vegetables instead. I often toss in some fresh spinach or sautéed mushrooms. Just make sure to cook the mushrooms first to get the water out. If you add raw veggies with a lot of water, your lasagna might get soggy. This recipe is very forgiving, so feel free to experiment with what you have in the fridge.

You can also play with the cheese. Mozzarella is classic, but a mix of provolone and cheddar is also very tasty. If you like things spicy, use a “hot” Italian sausage instead of beef and add some red pepper flakes to the sauce. I once used pumpkin ravioli in the fall with a white creamy sauce, and it was a huge hit. The base method stays the same no matter what flavors you pick. It is a great way to use up leftovers or try new things without much risk. This dish is for everyone, from picky kids to hungry adults.

How to Serve Your Casserole

This casserole is very filling on its own, but it is even better with a few sides. I usually serve it with a simple green salad. A crisp salad with a vinegary dressing helps cut through all that heavy cheese and meat. It makes the whole meal feel a bit lighter. I also almost always make garlic bread. You can buy the frozen kind to keep with the “lazy” theme, or just toast some sliced bread with butter and garlic salt. There is nothing better than using a piece of bread to soak up the extra sauce at the bottom of your bowl.

If you are serving this for a party, you can set out extra parmesan cheese and some red pepper flakes on the table. This lets people customize their own plate. For a drink, I like cold sparkling water with a lemon slice. Since the meal is so warm and savory, a cold bubbly drink is very refreshing. This is a heavy meal, so you do not need much else to be full. It is the perfect comfort food for a rainy day or a Sunday night dinner before the busy week starts. FYI, kids usually love this because it is easy to eat with just a fork.

Why This Works for Busy Families

As a cook, I have learned that the best meals are the ones that actually get made. Sometimes I have big plans for a 20-step recipe, but then I get home from work and I am just too tired. When that happens, I usually end up ordering expensive takeout. This lazy lasagna saves me from that. It takes almost no brain power to put together. Because it uses mostly pre-made ingredients like frozen ravioli and jarred sauce, the quality is very consistent. You know exactly how it will taste every time you make it.

It also makes a lot of food. One pan can easily feed a family of four for two nights. I love “planned leftovers” because it means I do not have to cook the next day. The flavors actually get better after sitting in the fridge for a night. The pasta soaks up more of the sauce, and the spices blend together. If you are a meal prepper, you can even put this together in the pan in the morning, put it in the fridge, and just pop it in the oven when you get home. It is a smart way to manage a busy schedule without giving up a good home-cooked meal.

Common Questions About Lazy Lasagna

People often ask me if they can use different types of pasta or if they can cook it in a slow cooker. I have tried many ways, and the oven is usually the best for the texture. However, the ravioli is the real key. If you try to use regular dry pasta without boiling it, you would need a lot more water in your sauce, and it might come out gummy. Stick with the frozen ravioli for the best “lasagna” feel. Here are some of the most common questions I get from my friends and readers about this specific recipe.

Do I need to thaw the ravioli first?

No! Use them straight from the freezer. Thawing them makes them too soft and they might break apart during the baking process.

Can I use spinach ravioli instead of cheese?

Yes, any flavor of ravioli works. Spinach or mushroom ravioli are great ways to add more vegetables to the meal.

How do I stop the cheese from sticking to the foil?

Spray the underside of the aluminum foil with a little bit of cooking oil before you cover the pan. This keeps the cheese on the pasta!

Can I make this in a smaller pan?

Yes, you can cut the recipe in half and use an 8×8 inch pan. The baking time will be about 5-10 minutes shorter.

Is this recipe spicy?

It is only spicy if you use spicy sausage or red pepper flakes. Otherwise, it is very mild and kid-friendly.
