Roughly chop and steam the onion, broccoli, carrots, cauliflower, zucchini, and quartered sweet potato until soft (about 10 minutes) in about 1-1 1/2 inches of water.
Add the spinach leaves/frozen peas and finish steaming until the spinach is just wilted (about 3 minutes).
While the vegetables are steaming:
Pour 1 jar of tomato sauce into a large bowl (with extra room for the ricotta/vegetables)
If you are using regular or vegan ricotta puree the ricotta ingredients in a blender then add to the tomato sauce bowl.
Puree the steamed vegetables in a blender (use up to 1/4 cup of water from the steamer to blend.)
add to the tomato sauce and ricotta bowl.
Add a thin layer of tomato sauce on the bottom of your pan.
Layer the lasagna noodles so they are overlapping a 1/2 inch for each noodle.
Spread a layer of cheese on top of each noodle. Spread a layer of sauce. Layer cooked meat if you are adding meat.
Repeat until all of your ingredients are gone
Top with cheese and sauce, put foil on the top of the casserole, and put it in the oven!
After 1/2 hour, reduce the cooking temperature to 350°F.
Cook an additional half hour, then let it rest for 15 minutes before slicing. This helps the layers congeal.
Take the 2nd jar of sauce and pour half on top of the lasagna and serve the other half in a bowl for dinner.
All done! Enjoy!! Now take a photo, rate it, and share your accomplishments! :) Tag @BlenderBabes & #BlenderBabes
Notes
If you like meat in yours, ground turkey was a big hit for the meatlovers version of this lasagna!
