How to Make Vegetable Lasagna with White Sauce 

These are the basic steps for making vegetable lasagna in white sauce. Please refer to the recipe instructions in the recipe card below for more detailed instructions and nutrition information. Check Instagram, Facebook and Twitter for more.  This 

Preparing the sauce, noodles for the lasagna.

STEP 1: BROWN

To make lasagna with sausage and vegetables, first, boil lasagna noodles in a pot of salted water. You can use uncooked lasagna noodles, as long as they are the oven ready lasagna noodles.  Then, in a large skillet, brown sausage over medium heat. Remove sausage from skillet and drain all but 1 tablespoon of drippings.

STEP 2: SAUTE

Make the cooked vegetable mixture – add onion and garlic and sauté until tender, about 2-3 minutes. Stir in sausage, red peppers and wine. Bring to a boil; reduce heat and simmer, uncovered, until the liquid is reduced by half – about 5 minutes.

STEP 3: MIX

Meanwhile, in a large bowl, stir in the spinach, ricotta and next 3 ingredients.

Preparing the filling for the lasagna.

STEP 4: LAYER

Spread 1 cup of the sauce on the bottom of a greased 13x9x2 baking dish. Add a layer of noodles (I used four) on top of the sauce. Putting a cup of the white sauce in the bottom prevents the lasagna from being dry on the bottom.  Spread half of the vegetable mixture on top of the noodles and then layer half of the sausage mixture on top.

Top with 1 cup of mozz. Continue layering the lasagna.  Spread the remaining sauce, add another layer of noodles, the remaining spinach mixture, sausage mixture and top with remaining noodles.  

STEP 5: BAKE

Top with remaining cheeses. Cover and bake lasagna at 350° for 1 hour, uncovering during last 15 minutes of baking. Let stand 15 minutes before serving.

Lasagna made with vegetables can get watery as the water from the veggies is released during cooking. The best way to keep vegetable lasagna from becoming watery is drain as much liquid from the vegetables as possible.  You really need to squeeze out the excess water from the spinach before adding it to the mixture.

    I just made this for company tonight and I didn’t follow the instructions to the exact measurement but it turned out great! I substituted yellow bell pepper for the red, and made a white sauce from a butter & flour rue with milk, I also just added my chicken broth to deglaze the pan and threw my chopped spinach into the broth to cook, then added the cooked sausage, onion and pepper back in then the cream sauce to that, I then layered the sauce on the bottom of the casserole dish and the next layer after noodles was my egg, cheeses(parmesan and mozzarella) and cottage cheese (instead of ricotta cheese) mixture, then noodles, more sauce, noodles and mozzarella as a topping! I then baked it immediately, It turned out great! Thanks!

  4. Hi, just want to clarify that noodles are not boiled? Place dry noodles straight from package during the layering process? Thanks!

  5. Where do I add the sausage sauce juice?? What does next three ingredients mean?? It would of been nice to know that it had to be refrigerated overnight. We are now dinnerless

    • I’m sorry you had trouble with this recipe. It’s always recommended that you read the entire recipe before you begin cooking so you’re clear about what’s involved. Here’s some clarification…Step 9 explains what to do with the sausage mixture. “Next 3 ingredients” refers to the next 3 ingredients in the ingredient list (salt, pepper and egg). Lastly, this recipe does NOT have to be refrigerated overnight. Step 13 states that you CAN refrigerate it overnight if you WANT to. You don’t HAVE to. It can be baked immediately after assembling it. Again, sorry for your troubles.

    • Step 7 mentions the Alfredo sauce….it’s part of the layering process. Use it like you would use marinara sauce in a traditional lasagna.

  6. Please let me know where the Alfredo Sauce is added…i am planning to make this meal Friday … I have purchased the ingredients

  7. I wanted to make this recipe this weekend. It looks fabulous! However, it only mentions using one cup of Alfredo Sauce on the bottom of the pan. The recipe calls for 2 17oz jars of sauce….Where does the other sauce go in the recipe besides the bottom?
