Slow cooker chunky marinara sauce, with tomatoes, bell pepper and onions {vegetarian, gluten-free}

Slow cooker chunky marinara sauce recipe, with any kind of pasta. #pasta #vegetarian

Two weeks ago my husband Ted spent a few days battling a nasty Spring cold. I plied him with soup, soup and more soup, but there came a moment when neither of us could stand the sight of another bowl of it. With comfort food on my mind, I ransacked the pantry and found all of the ingredients for this recipe, a very traditional meatless marinara sauce. I tossed everything into the slow cooker for six hours; then I added the magic ingredient, the rind from a small wedge of Parmigiano-Reggiano cheese, and continued to cook the sauce for an additional two hours. (For a vegan sauce, simply omit the cheese rind.) You can make this marinara recipe exactly the same way in a Dutch oven on the stovetop, except that you'll have to stir occasionally to keep the sauce from sticking. Pour the sauce over a bowl of spaghetti or gluten-free pasta, top with more parmesan cheese, and let the comforting begin.

I am craving something with marinara sauce now, maybe spaghetti squash! The touch of Dijon is a brilliant addition.

Kalyn, this is one of those sauces that's so great to make ahead and freeze in small portions, for anything from pasta to omelets.

This is definitely my kind of comfort food!

Carol, same here!

Looks yummy! Love the chunky texture! I will give this a go. I never used celery in mine, so that is a nice addition too!

Winnie, I love the chunky texture, too. If that's not your thing, you can take an immersion blender to it at the end, and smooth it out.
