Slow Cooker Summer Lasagna

Summer Slow Cooker Lasagna with Zucchini and Eggplant
Have you ever made lasagna in your slow cooker? Up until the last few months, I was completely skeptical about the idea. I get a lot of use out of my slow cooker, especially on busy weekdays, but for pasta? I wasn’t so sure.

Now, I’m a convert. The slow cooker makes the process really simple: no boiling noodles, and no need to worry about making neat layers. It’s especially nice during the summer, since there’s no need to turn on the oven.

Before assembling this slow cooker lasagna, you will need to first cook some veggies (summery favorites like zucchini, eggplant, corn and tomatoes) in a skillet to cook off some of the liquid and keep your lasagna from being watery. Then you’ll spread a thin layer of sauce in the bottom of the slow cooker and top with several uncooked lasagna noodles, breaking them as needed to fit. I like to overlap the edges just a bit, but there’s no need to be perfect and fill every little crevice with a noodle.

The rest is easy: layers of veggies, sauce, noodles and cheese, just like a normal lasagna. The final layer includes a bit of panko breadcrumbs, which will help make the top slightly crunchy.

I recommend checking the lasagna at the 3 1/2 hour mark, to see if the pasta is tender. Don’t overcook the noodles—no one likes mushy lasagna!

Print recipe

instructions:

  1. Set a large skillet over medium heat. Add in the olive oil. When hot, cook the onion in the oil for 2 to 3 minutes, until it starts to soften. Add in the zucchini, eggplant, corn, tomatoes, garlic, salt and red pepper flakes. Cook for 7 to 9 minutes, until the veggies are tender. Remove from the heat, taste and season with additional salt and red pepper flakes if needed.
  2. Spread 1/2 cup of the sauce in the bottom of your slow cooker. Top with a layer of three lasagna noodles, breaking them as needed to fit. Using a slotted spoon, top with 1/3 of the vegetable mixture, then 1/2 cup of the sauce and 1/3 cup of the mozzarella cheese. Repeat this process two more times -- noodles, vegetables, sauce, cheese. End with a final layer of noodles and the remaining 1/2 cup of the sauce. Sprinkle the top with the remaining 1/3 cup mozzarella, the parmesan and panko.
  3. Cover and cook on low for about 3 1/2 to 4 hours, until the noodles are cooked through. Turn off the slow cooker and let sit uncovered for 20 to 30 minutes before serving. This will let the lasagna set so you can cut it easily and it will hold its shape. Sprinkle the top with fresh basil before serving.

notes:

Make sure you use regular uncooked lasagna noodles. Do not use the no-boil kind. For the canned tomato sauce, I used around 1 (15 ounce) can and 1 (8 ounce) can to get this amount. It is possible to find vegetarian parmesan cheese in the US (such as the Whole Foods 365 brand or Organic Valley). Outside the US, look for vegetarian hard cheese to use instead.

Just the photo of the veggies in that slow cooker make my mouth water — I’m definitely trying this! I love the no-boil lasagna thing, and no oven in the summer is a must! 🙂

This looks delicious! The colors of all the different veggies are gorgeous. So glad I found your blog (Pinterest). It has been tough for me to get the support to eat more veggies and less/no meat so any recipe that is fulfilling to the tummy, but also the eye, is a win for me! Thanks for sharing an easy veggie lasagna!

Thanks so much Megan! It’s a great way to get a bunch of veggies in one dish! And I’m with you – I love pretty looking food! 🙂

It’s a great recipe to play around with to your own preferences – you can definitely add more sauce to get it to your own taste!

Well, leave it to me to not read til the end. I did use no boil noodles because that’s what I had in the house. Hope I didn’t spoil it!!

Hi Diane! It should be okay – I would just start checking it a little earlier – I’m thinking around the 3 hour mark to see if the noodles are done!

I also accidentlly used the no boil noodles. Mine turned out grew it was just done faster, took about 2 1/2 hours. Thanks for a great recipe !

Thanks Joanne! It’s so nice not to have to turn on the oven! Especially right now with all the humidity!

What about all the water from the eggplant and Zucchini? Doesn’t it come out all watery? How can I prevent that – i would love to make this. Thx.

Nope! Since you are cooking the veggies in a skillet first to get rid of the excess moisture, you don’t need to worry about that. That step prevents it from getting all watery!

I cannot wait to make this tonight! Since corn is no longer in season, I think I’m going to swap it out for delicata squash. Just wondering if anyone has tried to incorporate fresh ricotta in this recipe? It’s hard for me to imagine an awesome lasagna without it, but I also can’t see how it would hold up in a slow cooker for 3 hours. Any ideas?

Hi Carly! I haven’t used the ricotta in this particular recipe but I have added it to other lasagnas that I’ve made in my crockpot. I’ve never had any problems with it in the slow cooker – always tastes great 🙂

I just made this, but substituted canned pumpkin mixed with almond milk for the tomato sauce. For the vegetables I used zucchini, onions and spinach. Daiya mozzarella cheese and no boil whole wheat noodles. It was excellent! Thank you for the recipe inspiration!

Hi Looks great, but how long if you cook it on low? Working 8 hrs , most crockpot recipes are for short periods of time 🙁 Thanks

Hey Barb! Unfortunately, yes, I would wait. Even on low this cooks pretty “fast” in the crockpot!

Used this recipe as inspiration today. Wound up out of the house longer than expected so yes the noodles were soft. I added slices of large portobello mushrooms as well and it turned out great. The mushrooms slices help to satisfy the meat eaters and keep the veggie fans happy too.

Next time I’ll set the timer to achieve firmer noodles but thanks for the inspirational recipe.

This recipe is amazing, and I much prefer the veggie lasagna to boring meat lasagna! I added Brussel Sprouts and Spinach in place of the eggplant. It is going to be my go to recipe.

For those who added spinach….how much and did you sauté it with the other vegies, or put it in raw?
