This vegan Kale Mushroom Gratin is truly comfort food at its finest! The creaminess and flavors of this dish will have you oohing and aahing with delight. It’s a meal that’s perfect for the cooler winter days and nights.

This recipe is inspired from Food 52 entitled, Spinach, Mushrooms and Cream for Dinner, which is adapted from Nigel Slater’s, Tender. I decided to veganize it and it’s definitely one of those dishes I will come back to again and again!

This Kale & Mushroom Gratin recipe is simple, easy to prepare and just about fool proof. You will not miss any of the standard dairy products typically used in dishes like this. And that I promise you!

I served my kale & mushroom casserole over a bed of farro but you can use whatever grain you like that fits into your dietary guidelines. Even mashed potatoes or pasta would be great!

Ingredients You’ll Need

Onion, mushrooms and kale are cooked until tender with wine and vegan cream and then baked until bubbly creating a simple, yet delicious, plant-based mushroom casserole that is perfect for both casual and elegant dining!

Here is everything you will need:

  • Mushrooms – brown mushrooms are best, and yield the most nutrients
  • Kale – use curly or flat kale, and for ease use pre-cut (also can sub with spinach)
  • Onion – small onion or large shallot
  • White wine – any vegan dry white wine will do
  • Vegan Cream – make homemade vegan cream or use store bought
  • Plant milk – use your favorite plain and unsweetened, I used cashew milk here
  • Salt + pepper – to taste

Can I add herbs or other flavors?

Yes, this recipe is very simple, but would do well with 1 teaspoon thyme or garlic powder for another layer of flavor.

  • Add kale, and continue cooking until soft, about 4 minutes.
  • Add the cream and milk, let simmer for several more minutes. Season with salt & pepper. Turn off heat. Tip: If you have time, leave this mixture to steep; the cream and milk will get wonderfully mushroomy.
  • Transfer the mixture to a shallow baking dish. Place in the oven and bake for about 25 minutes, or until golden and bubbly. Let cool a few minutes before serving.

And now your creamy gratin is ready!

How To Store Leftovers

  • Refrigerator: Leftovers will keep for 5 days in the refrigerator, stored in a covered container.
  • Freezer: This mushroom gratin is freezer friendly and freezes well for up to 2 – 3 months. To freeze, let cool completely and store in freezer safe containers (affiliate link), leaving 1/2 inch head space for expansion. Let thaw before reheating. You can also freeze larger portions in large ziplock bags.
  • Reheat: Simply re-warm on the stovetop over low heat until warmed through, adding a little plant milk for moisture as needed. Alternately, reheat in the microwave using 30 – 60 second intervals, stirring after each, until warm.

Can I Make This Mushroom Gratin Ahead?

Yes, you can make this vegan gratin ahead of time. It will be even better as the flavors will have time to steep together. To make ahead, simply prepare as directed, cover and keep in the refrigerator or freezer until ready to bake.

Serving Suggestions

This savory and creamy gratin can be served in a variety of ways for a hearty plant-based main meal. Here are a few of my favorite options:

  • Grain: Serve on a bed of Farro, quinoa, white rice, brown rice, or even black rice.
  • Pasta: Serve over pasta such as orzo, couscous, bowtie, penne, linguine, fettuccini, and more.
  • Bread: This would be great served over toasted and lightly buttered homemade Artisan Bread!
  • Vegetable: Serve topped on a baked potato, Mashed Potatoes or Oven Roasted Red Potatoes. Or with a side of Green Beans Almondine.

  1. My Partner and I are doing veganuary. I’ve actually been searching for something to replace our breakfasts. Many of the recipes I’ve seen are sweet, which we’re not a fan of. I’ve also been worried about misssing the unctuousness of egg yolk. This recipe was perfect served on some sourdough toast as a savoury breakfast. I didn’t miss the eggs at all. And the bonus is that it’s better if you make it the night before, and just bake it the day of eating.
    This recipe will definitley be appearing in our regular rotation, especially in the late winter months, when kale and other brassicas are pretty much the only things coming out of the garden in the hungry gap.

  2. I added a bit of garlic, but otherwise kept everything as is and it was delicious!! Served over barley and it was a hit. Will definitely be making again. Thanks!

  3. Sherri Neil says:

    I just want to say thank you. My husband is not a big fan of kale,so I thought maybe this would hide it a little. He loved it and then I told him there was a lot of kale in it. He could not believe it. This is definitely a keeper.

    1. Julie | The Simple Veganista says:

      I’m so glad you both enjoyed this creamy kale recipe! Thanks so much for sharing, Sherri! Cheers :)

  4. Tessa Webb says:

    This recipe was AMAZING! I made it yesterday for my boyfriend and me and he told me afterwards that it was one of the best things he has eaten recently — and I agree! This is sooo creamy, filling but not too heavy, great flavors, and easy to make. I added a lot of garlic because we love garlic (who doesn’t?!) and served it over orzo. Absolutely amazing — definitely added to our regular meal rotation!

  5. I needed to find a new way to prepare mushrooms and kale and decided on this recipe. It is absolutely delicious. I served It over penne. The almond Parmesan was a wonderful addition! This is a keeper!

  6. Oh my!! I highly recommend this. I received two large produce boxes this week and had an abundance of kale and mushrooms. I went looking for recipes on the Google machine and this one caught my eye right away. I don’t have any white wine so I just added a little bit of water to ensure the mushrooms and onions didn’t burn. It was so good I posted it on two Facebook groups as well as my page to tell others about it. It’s been a while since I was THIS excited about a recipe. Yum. Make it!

  7. My husband and I are new to plant based/vegan eating. I find I have to cook all the time as we are trying to eat more whole foods rather than processed. We rate all the recipes we try on a scale of 1-10 and we both gave this one a 10! Delicious and comfort all in one dish!
    We have found many great recipes on your site, Thank you!

    1. Julie | The Simple Veganista says:

      Thank you for sharing, Judy! So glad this worked well for you, makes my day. Be healthy and well!

  8. Delicious! I served this with mashed potatoes and both my husband and I loved it. Thanks!

    1. Julie | The Simple Veganista says:

      Thank you for sharing, Oano! That sounds wonderful, I’ll add them to the serving suggestions!

  9. I was actually planning to make your mushroom soup, but I saw this recipe and I had a big bag of kale in the fridge, so decided to give this a try. Oh, my!!! It was absolutely delicious! Thanks so much. I’ll definitely be making this one again.

  10. Vegan Parmesan is non existent where I live. Any other suggestions for a topper?

    1. Julie | The Simple Veganista says:

      Hi Stefanie, I would suggest maybe making your own with one of the recipes in the TSV archives, Almond Parmesan. It will be amazing sprinkled over top of this gratin!
