Lasagna is my husband’s very favorite meal. He asks for it with every birthday that passes. I have made it more than a dozen different ways but this one might be the real winner. Its a combination of Italian sausage, summer squash and roasted tomato sauce with plenty of cheese! And its pretty easy to put together this Summer Squash & Sausage Lasagna – you could definitely make it on a Weeknight.

We had an abundance of summer Squashes in our garden this year, so I was looking for ways to creatively add them to meals we already love. When you slice the squash very thin on the mandolin, they almost dissolve into the sauce. It adds an earthy depth of flavor to a delightfully fresh take on homemade lasagna. My kids didn’t even realize it was in there until they were done eating and I told them. They felt a little tricked but ultimately admitted they still loved it. So if you have to “hide” veggies in your meals for the kids *(or maybe the adults too!, no judging), then this is a really great recipes for you and yoru family.
Substitutes and Variations:
I imagine you could swap out the summer squash for Zucchini and get a really great flavor. I have included my recipe for roasted tomato sauce (which I can into quart jars and have on hand most of the year). But you could really use any of your favorite jarred sauces in this one. You could also swap out the sausage links for crumbles of sausage or ground beef.
Suggestions for Sides:
I served this with some paremsan garlic toast made from sourdough bread. It was so good to soak up the extra sauce with. You can also do a classic garden salad or caesar salad to go with it. Since there are already veggies in the lasagna, you may not get away with another veggie on the side, but you always do some sauted carrots or green beans.
Tools that may make this recipe easier:
You will need a mandoline to make the thin slices of the both the red onion and the summer squash. If you do not have a deep 13×9 casserole dish, you can use a disposable foil one. I actually prefer this because it makes clean-up so much easier.
Now Let’s Get Cookin’!
