    I am in love with caramelized onions. If they didn't take so long to cook, I'd probably make them more often. Their sweet rich flavor takes ordinary dishes to a whole new level.

    Sometimes the simplest meals are the best ones. That is the case here. This vegan Caramelized Onion and Mushroom Pasta is super easy to make.

    Yes, it takes some time to caramelize onions, but man is it worth it.

    Red wine adds another dimension of flavor. Mushrooms go well with caramelized onions, adding an umami flavor.

    You could also use other veggies, like asparagus or bell pepper. Serve it with a Jar of Sangria.

    Other recipes to try are my Silken Tofu Macaroni and Cheese and Vegan Taco Pasta recipe. Another recipe with caramelized onions is my Vegan Mashed Cauliflower with Mushrooms recipe.

    ❤️ Why You'll Love It

    • It is rich and savory.
    • It's perfect for date night.
    • It's a simple and easy meal with a balance of flavors.

    🧾 Ingredients

    Caramelized onion and mushroom pasta ingredients on a cutting board with labels.
    • Pasta: I used brown rice gluten-free pasta noodles. Use your favorite pasta.
    • Olive oil: For cooking the onions.
    • Onion: I used yellow onions. You could also use sweet onions, just keep in mind the caramelized onions will be even sweeter and you may not want to add the brown sugar.
    • Brown sugar: Adds sweetness to the caramelized onions. You could also use balsamic vinegar, which I've used in the past.
    • Mushrooms: I used baby bella (cremini mushrooms). You could also use portobello mushrooms or your favorite.
    • Red wine: Use a red wine that you would actually drink. It doesn't have to be expensive, just flavorful and decent quality.
    • Nutritional yeast: Adds a cheesy flavor. You could also use store-bought vegan parmesan cheese. It's optional.
    • Parsley: For topping. Adds a fresh note.
    • Salt and pepper: Enhances flavors and adds flavor. I like to use sea salt.

    💭 Tips

    • When making caramelized onions, slow and steady wins the race. For caramelized onions, you need some patience. It takes a good 35-40 minutes to get nicely caramelized onions.
    • Use a wine that you would actually drink (and since you don't use much for this recipe, you'll be drinking it).
    • Don't forget to salt your pasta water!
    • Balsamic vinegar adds a wonderful flavor. I always add a couple of splashes near or at the end of the cooking time. Alternatively, you can add a couple of pinches of sugar or brown sugar. I only had brown sugar when updating this recipe, so that's what I used.
