    Creamy Vegan Spaghetti Squash Bake

    A close up of creamy vegan spaghetti squash, wild mushroom, and spinach bake with a spoon.
    Ok – so this recipe is one of those to keep on hand when you really need to go all out and splurge, but probably shouldn’t. So first thing that makes this recipe awesome is that it is creamy AF – like so creamy, and it tastes super creamy too, like the real deal creamy. We used the magic of nutritional yeast. Then to make this recipe even more awesome instead of pasta we used spaghetti squash. In this situation where it is baked in with this yummy sauce and some veg, you really don’t miss real pasta. There is no need for it. So just keep this recipe on hand for the times you really want to go for it, but don’t need to go for it. :)

    RECIPE BY Teri & Jenny
    Servings: 8 servings

      INGREDIENTS  

    • 1 medium spaghetti squash
    • 2  tablespoons extra virgin olive oil (coconut oil is fine)
    • 3 garlic cloves, thinly sliced
    • 1 large shallot, minced
    • 12 cremini mushrooms, cleaned and sliced
    • 12 shiitake mushrooms, cleaned stemmed and thinly sliced
    • 12 ounces baby spinach

    cauliflower “cream” sauce

    • 1 1/2 tablespoons extra virgin olive oil ( coconut oil is fine)
    • 2 tablespoons vegan butter
    • 1 small shallot, diced
    • 2 garlic cloves, minced
    • 1 head cauliflower (about 1 1/2 pounds), cut into bite sized pieces
    • 1 teaspoon dry mustard
    • 1 ½ cups warm vegetable stock, plus up to 1 cup more as needed
    • 5 tablespoons nutritional yeast
    • salt and pepper to taste

      INSTRUCTIONS  

    • Preheat oven to 375˚F.
    • Slice squash in half lengthwise and place onto a baking sheet, cut side down and roast for about 1 hour or until squash becomes fork tender.
    • Allow squash to cool for about 15 minutes, before scraping the flesh out with a fork (squeeze to drain any access liquid from squash). Place squash innards in a mixing bowl, lightly season with salt and pepper and set aside.
    • Place a large skillet over medium-high heat and add oil. Sauté garlic and shallot for 2 to 3 minutes. Add mushrooms and continue to sauté for 3 to 4 minutes or until caramelized.
    • Add spinach and continue to sauté for 2 to 3 minutes or until spinach has wilted. Drain excess liquid and stir mixture into the mixing bowl with spaghetti squash.
    • For ‘cream’ sauce: Pour 1 ½ tablespoons oil into the pot and place back over medium-high heat. Add shallot and garlic and sauté for 2 to 3 minutes.
    • Add cauliflower, continue to sauté for 2 to 3 minutes and season with salt and pepper. Stir in mustard and continue to sauté for 2 to 3 minutes.
    • Pour 1 ½ cups stock into the pot and simmer until cauliflower becomes fork tender, 6 to 8 minutes.
    • Carefully ladle mixture into the well of a blender and add nutritional yeast. Blend on high, adding more stock as needed. With the motor running, add vegan butter and season with salt and pepper. Blend until a smooth, glossy and creamy sauce forms.
    • Pour sauce over the spaghetti squash mixture and toss together until fully combined.
    • Pour mixture into a lightly greased baking dish and bake for 15 to 20 minutes or until the top has lightly browned.
    • Allow bake to cool about 10 minutes before serving.

      Had a spaghetti squash laying around yesterday on Thanksgiving and wanted to try something new. I made it exactly like the posted recipe cause I had never made anything with this type squash ever! It turned out really good and was our main course yesterday. The creamy cauliflower sauce was like heaven. If you’ve never tried this veggie before this is a great introduction recipe to get u hooked on it.

      Would it be possible to prepare this all the way up to the point right before you bake it in the oven? Would love to prep this earlier in the day so I can just pop it in the oven to bake after work for a quick dinner. Wasn’t sure if the spaghetti squash would get over saturated if I did this. Thanks!

      I loved the recipe- but I’d like to brighten the flavor a tad- what do you think about adding a tad of lemon zest to the sauce. We topped it with cauliflower crumbs and vegan gluten free crispy onions

        Cheryl – That sounds like a delicious idea! Please report back if you end up adding lemon zest, we would love to hear how it turned out!

      Making this right now! It looks like you topped yours with breadcrumbs but I don’t see this in the recipe. Did you use breadcrumbs on top?

        Hi! Thanks for pointing that out! Yes! I topped ours with about 3/4 cup of panko breadcrumbs tossed together with about 1 tablespoon melted vegan butter. Melted coconut oil can be used as well!

          Shoot wish I would have known it was topped with breadcrumbs. I wanted to photograph it for IG but it really looked nothing like your picture. At any rate. I’ll know for next time. I don’t know why I did not think to top it with anything. My bad!

      Hi!

      The recipe says:

      2 tablespoons unsalted butter
      2 tablespoons extra virgin olive oil or coconut oil

      Where do I put the vegan butter in? I do not see it in the directions

        Hi! The butter in the recipe is the vegan butter. I will update the recipe to make that a little more clear!

      I love this dish. I’ve cooked it once and made too much cauliflower sauce, but it is so good. I cannot wait to try it again and measure better! Thank you.

      Made this last weekend and was surprised that it fills an 8×13 pan! Luckily, a friend of mine dropped by and had some — and loved it so much that she took some with her — because I’m just one small woman with a small freezer. Anyway, I’ve had it hot out of the oven, and I’ve reheated it at work, and I am happy to report that both ways it was very good. It’s a little too rich for me in large amounts, which is a very strange thing to say considering it’s all vegetables, but I put some roasted broccoli on the side and it was perfect. My doctor just put me on a vegan diet, so this recipe really was a godsend. Would definitely make it again. Thank you!

      Wow! This looks great! Did you add breadcrumbs to the top? Also, do you think I can leave out the tablespoon of oil that you add to the sauce? I’m trying to cut out oil from my meals. Thanks!

        I cut back on the oil in the first area, cooking the mushrooms. I think the oil in the second is necessary to get a creamy sauce, but only add what you want. I used coconut oil in my frying sections.

      I made this last night. I thought I was doing well until I finished making the cauliflower cream sauce…It never got creamy…? I blended it for quite sometime… Is there something I missed? I followed the instructions verbatim, but it did not say how long to blend. It didn’t taste good to me… But maybe I just don’t like this taste?

        We’re in the throes of finishing the veggies now to throw it in the oven. Be careful with how long you cook the cauliflower and how high the temperature is. It can get starchy if overcooked and it’ll never get to the right consistency if that happens. Definitely give it another shot, the sauce is truly delicious! Great recipe, thanks Jenny!

        I used a food processor not a blender and it worked like a charm. You have to make sure ur cauliflower is super tender.

            Yes, definitely! I would just undercook the spaghetti squash slightly so it doesn’t turn ‘mushy’ when thawing/reheating!
