Slow Cooker Sausage and Vegetable Ratatouille

Total Shares 764

Do you use your slow cooker a lot over the summer? I have big plans to use my slow cooker at least once a week this summer. As I have mentioned before, our house (especially the kitchen!) heats up pretty good during the day in warm weather and since we don’t have air-conditioning on that floor, turning on the oven only exacerbates the situation and raises the temperature significantly.

This Slow Cooker Sausage and Vegetable Ratatouille is ridiculously easy, loaded with vegetables, dairy free, paleo and can be served alongside a simple side salad, over cauliflower rice, regular rice or even some zucchini noodles!

This is the fourth time I’ve made it and I’ve tried a couple of different combinations of vegetables (this is my favorite by far!) and types of sausage. If you wind up with leftovers, this freezes great and make a perfect at-work lunch!

Slow Cooker Sausage and Vegetable Ratatouille from www.EverydayMaven.comNOTES:

  • I used Trader Joe’s Arrabiata Sauce. You can use any jarred pasta sauce (or homemade) that you like, just look for one that doesn’t have additives, preservatives or a ton of sugar.
  • I have made this with mild sausage, spicy sausage and even chicken sausage. The spicy pork sausage was by far the best and my families favorite. If you don’t eat pork and want to use either chicken or turkey sausage, I highly recommend you use a spicy sausage. The end result of this dish will not be super spicy since the vegetables are so water-rich and the spices in the sausage really help add another layer of flavor to the dish.
  • I used a 6.5 Quart Slow Cooker.
  • In regards to the cooking time, I have found this is best cooked on high for 4 hours. I have tried it on low and you can cook set the slow cooker for 8 hours while at work or out but you will need to put it on high for at least 1 to 1.5 hours before serving it.
  • If you are making this while on a Whole30, be sure to use a Sugar-Free sauce!

    So it turns out I don’t like eggplant (never had it before this and obviously not the recipe’s fault) but after picking around it I am still in love with this recipe. I will be making it again but probably using summer squash instead of the eggplant and keeping the recipe the same. I used half Rao’s Arrabbiata sauce and the other half the Rao’s Tomato Basil to keep the heat in check as hubby isn’t a big fan but this was seriously nummy!

    Just want to tell you I have made this weekly since you posted. It’s definitely a staple in my household now. Thank you!

    I love the fresh, seasonal approach you took with this slow cooker dish. It’s perfect for when I want a healthy meal, but need to be in the office for a long day. This was a huge hit with my family, especially my 11 year-old son, who is working on becoming a veggie fan. He asked me to make it again this week. Thanks so much for your work and for sharing this recipe!

    This is a fabulous recipe, Alyssa! I made it early this morning, put it in the fridge and then reheated some of it for dinner. I had it over some leftover green beans.It makes a ton but it’s so good I’m reluctant to freeze any of it – perfect for lunches at work. I don’t like spicy things so used organic chicken sausages and a tomato basil sauce. It’s so flavorful and unbelievably easy and quick to assemble. This is the second recipe of yours I’ve made (the other one was the salmon cakes) and you are an amazing cook. Thanks for sharing these recipes.

    Ok…Thanks! This looks great. Do I need to brown the sausage first? Or does it cook in the crock pot? I am looking forward to making this!

    • says

      Sure! I just updated the recipe to say “uncooked, crumbled sausage”. Sorry about that. Yes, use raw sausage and it will cook along with the veggies and give off some yummy flavor. Enjoy!

    As soon as I saw this I wanted to make it. I made it today and it is one of the tastiest dishes I’ve tried. The combination of vegetables with the spicy sausage and the Aribiata sauce was delicious. I was able to fill two quart sized containers to share with my sister and to enjoy for the next few days. Thanks for sharing your recipe:)

    Hi Alyssa! Personally, when I was following WW, I would have a smaller portion and bulk up my 0 PP veggies OR use some of the weekly points if it was really worth it. Good Luck!

    Hey– I’m looking for the same thing..
    can’t see the weight watcher PP or the nutritional info. Hmmmmmm, maybe i’ll check back for the update a little later Thanks!

    This looks delicious. Do you post the nutritional information for your recipes? Or the WW points plus values? I’d love to know the nutritional info for this recipe. Thanks!
