  • 8 oz cremini or button mushrooms, sliced
  • 5 tablespoons olive oil, separated
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon kosher salt
  • Fresh cracked pepper
  • 3 tablespoons all-purpose flour
  • 1 1/2 cups unsweetened almond milk
  • 2 cans cut green beans, drained
  • Dash of hot sauce or sriracha, optional
  • 1 1/2 cups fried onions


  • 1
    Preheat the oven to 425°F.
  • 2
    Toss mushrooms with 2 tablespoons of the olive oil and a pinch of salt and pepper, roast for 15 min.
  • 3
    While they roast, make the sauce. Combine the remaining 3 tablespoons of olive oil with the garlic powder, onion powder, kosher salt, and a couple cracks of black pepper in a medium saucepan. Turn the heat on to medium and warm the olive oil. You don’t want it super hot, just warmed up.
  • 4
    Add the flour, whisk to combine, and cook for about 3-5 min until color gets a little darker.
  • 5
    Slowly add the almond milk while whisking and cook for approx. 5 minutes so it gets thicker.
  • 6
    By now the mushrooms should be done so lower the oven to 350°F and add the mushrooms to the sauce with the green beans and the optional hot sauce.
  • 7
    Place in a greased 8x8” baking dish and top with the fried onions. Bake at 350°F for 15 min, or until the onions get nice and toasty.

More About This Recipe

  • Even though it might seem a long way away, Thanksgiving is right around the corner – waiting to peek-a-boo and stress everyone out, then put them in a food coma. One thing that might add to the mix is the growing number of family members that are either vegetarian or vegan. I’ve got a little help for that with one of my favorite Thanksgiving sides: Green Bean Casserole. But this version’s been veganized! We’re going with almond milk for creaminess and Green Giant canned green beans (because I can only eat green bean casserole with canned beans). There are also some mushrooms that’ll get their roast on in the oven to up the flavor, because I LOVE ROASTED MUSHROOMS. Bake for 15 minutes and then it’s straight to the Thanksgiving table – or any dinner table, in fact. November’s vegan month, so go out and try something new!
