Why I Love This Recipe

- Feeds a crowd: This recipe makes a lot of lasagna. Perfect for feeding a crowd (or having amazing leftovers)!
- Family favorite: Anytime I tell my family I’m making this lasagna, I get a resounding “YES!” from everyone. It’s one of my easy weeknight go-to’s.
- Meal prep win: Leftovers reheat beautifully and taste even better the next day!
The Ingredients
- Ground turkey: I like dark meat for flavor and tenderness, but you can swap in ground beef or Italian sausage.
- Tomatoes and tomato paste: Drained diced tomatoes and tomato paste create a rich, thick sauce that clings to every noodle layer.
- Italian herbs and garlic: Classic flavors that make your kitchen smell amazing.
- Cottage cheese and eggs: Lighten things up and create a creamy layer that’s similar to ricotta (but more budget-friendly!).
- Mozzarella and parmesan: For that perfect cheesy pull and salty finish.
- Lasagna noodles: Regular dried noodles. No need for “oven-ready.” Break them to fit your slow cooker.
Variations and Substitutions
- Protein swaps: Use ground beef, Italian sausage, or a mix of both instead of turkey if you prefer.
- Vegetarian version: Skip the meat and layer in sauteed spinach, mushrooms, zucchini, or lentils for a veggie-packed lasagna. Or just make my Crock Pot Veggie Lasagna!
- Cheese options: Swap cottage cheese for ricotta or even a mix of ricotta and cream cheese for extra richness.
- Gluten-free: Use gluten-free lasagna noodles. No need to pre-cook, just layer them in as usual.
Step by Step Instructions
- Cook the turkey: Heat 1 tablespoon of oil in a large sauce pot over medium heat. Add the turkey and cook for 5 minutes, until cooked though, breaking apart any chunks with the side of a wooden spoon to make bite sized pieces. Remove the turkey to a plate, and then drain the liquid.
- Make the sauce: Add the remaining 1 tablespoon of oil to the pot, then onions and cook for 5 minutes, until soft. Add the garlic and cook for 1 more minute. Return the turkey to the pot, add the drained tomatoes, tomato paste, salt and Italian herbs. Bring to a boil, and cook for 3-5 minutes, until the sauce thickens slightly.
- Mix the cheese filling: In a bowl, whisk the eggs and mix in the cottage and parmesan cheeses.
- Layer in the slow cooker: Spread a thin layer of sauce in the bottom of the slow cooker. Add a single layer of the dried lasagna noodles (I break them into pieces and slightly overlap to fit the crock pot), 1/3 of the cottage cheese mixture, and 1/3 of the mozzarella cheese. Repeat layering until you have 3 layers of each, ending with mozzarella cheese.
- Cook, rest & serve: Cover and cook on low for 4-6 hours until the noodles are tender. Turn off the crock pot, remove the lid, and allow to rest for 20 minutes before serving. This will help the lasagna keep its shape.

Notes
Note: My crockpot is 6.5 quarts. You may need to use less per layer to fit a smaller crock pot.

I’d like to cook in oven in a casserole dish. What do u suggest?? Also the veget lasagna
Just got the Weelicious cookbook after feeling some harsh mother’s guilt when I was packing the same thing for my daughter for lunch at daycare day after day. I love it! Now I’m loving the delicious recipes on your site. Looking forward to making this one!
Ok, so, first off, Crock Pot vs Slow Cooker….
My hubs nitpicks on this one a lot. 🙂 Kleenex vs Tissue, Q-tip vs cotton swab, Coke vs pop/soda. Part regional, part common usage, it all boils down to brand vs product. Most people would ask for a kleenex rather than a tissue, no matter the brand in the box because kleenex has become synonymous for tissues, who doesn’t call a cotton swab a tooth pick these days? And a Crock Pot is simple a brand of slow cooker. 🙂
That said, OMG THAT LOOKS AMAZINGLY GOOD! I just got myself a new to me crock pot at a yard sale recently so I’m looking forward to trying it out! Might have to be with this recipe!
My son has an egg allergy, can the eggs be omitted or is there a substitute I can use? Thanks!
This turned out delicious, but I would love to see a video of this (or your veggie lasagna) for proper technique. I think I really screwed up the proportions because I had a whole lot of the tomato sauce leftover (enough to make a whole pot of spaghetti with…) but didn’t seem to have enough of the cheese mixture. However, the flavor is great and we’ve been happily eating it as a leftover for days!
This is one of my first slow cooker successes! Thank you!! 🙂
I LOVE that you made this in a slow cooker. Basically you are a genius.
12 layers? This lasagna is kind of epic!! 🙂
Made this yesterday it was very good. I think my crock pot must cooks fast, I had it on low for 4 1/2 – 5 hrs and it was a little burned on the bottom. so it was a little dry, next time less time and I will add mushrooms. Nice coming home and dinner was ready!!!
My mother-in-law taught me to make oven lasagna with dry noodles 43 years ago. She passed in July last year. Miss her. Will make this for ease but will use homemade low fat ricotta. I love the stuff.
I would use a 28 ounce can of unseasoned tomato sauce in place of the tomatoes!
This recipe is awesome! I’m so excited to try it this week! However, one little issue… My 2 year old recently won’t go near anything with tomato chunks. Could I just omit the diced tomatoes? Or would I need to add something else in its place to get the right consistency?
Oh my goodness. You saved my life! My husband has been asking me to make lasagna for the past 4 months. I just haven’t had the time to get it made. I am so grateful for you n posting this genius idea. Looove.
I need to try this one. I’m a lasagna fanatic. Can’t get enough of it.
