Pull out your slow-cooker- it’s lasagna time!
There’s a theme around here, if you haven’t noticed. I’ve been making my favorite comfort foods with a giant easy button. Instead of tacos, we’re doing taco potatoes, instead of spring rolls, I made a spring roll salad and now, instead of lasagna, I’m making lasagna soup.
BL asked me what exactly lasagna soup was and I replied, tomato-vegetable soup with broken lasagna noodles and a dollop of ricotta cheese on top. You get where this is going, right? All the flavors of lasagna with a fraction of the work.
I apologize. I still love to cook but over these last few weeks of being very pregnant, between extra swollen feet, sore hips and a tired back, I looked for every shortcut imaginable. I’m fairly certain this is going to be the case from here on out, what with a newborn and all. Lemme know when I should expect to feel back to normal; 15 years, give or take?

Slow Cooker Lentil Lasagna Soup
This soup is so incredibly delicious (and easy) that I hope you’ll put it on your menu for the weekend.
A base of sauteed vegetables gets cooked with lentils in a fragrant tomato broth. Then, we add in broken lasagna noodles (or, any kind of noodle) and let cook until soft. Spoon into bowl and top with a dollop of ricotta cheese. While I used regular cheese here, it’s super easy to make dairy-free. I have a tofu-ricotta recipe here and I love this one using cashews.
One other tip – don’t be afraid to really break-up the noodles before adding them to the soup. They will plump up a lot when cooking and I found that smaller pieces were better for eating. If you don’t feel like using lasagna sheets, elbows, ditalini or another small noodle would work just as well.



Hope you love this one as much as we did. xo
