What are Kale and Mushroom Gratin?

Kale and Mushroom Gratin is a delightful dish that marries earthy mushrooms and hearty kale under a creamy, golden-brown topping. Traditionally, gratins feature a rich cheese sauce baked until bubbly, but this version takes a delicious twist to make it completely plant-based while retaining that comforting essence we all adore.

The combination of flavors offers a fantastic balance of umami from the mushrooms and a slight bitterness from the kale, creating a symphony of taste that is both rich and satisfying. The texture is equally pleasing: creamy and velvety from the vegan heavy cream, set against tender yet slightly crunchy greens.

This dish shines during family gatherings or as a cozy weeknight dinner, perfect for any occasion when you crave a little extra nourishment and comfort.

Ingredients

To make your own Kale and Mushroom Gratin, you’ll need the following ingredients:

  • 1 tablespoon olive oil or water for sautéing
  • 1 small onion or large shallot, diced (Choose large shallots for a sweet undertone)
  • 1 lb. mushrooms (cremini or baby bellas, sliced or quartered – the more the merrier!)
  • 1 lb. kale, stems removed and chopped (Lacinato kale is my favorite for this dish!)
  • 1/4 cup white wine (Use one you enjoy drinking, like a crisp Sauvignon Blanc)
  • 1 cup vegan heavy cream (recipe in notes—homemade is lusciously creamy!)
  • 1/4 cup unsweetened almond milk (or any other plant milk you prefer)
  • Himalayan salt to taste (Sea salt works too)
  • Cracked pepper to taste
  • Almond Parmesan for serving (adds a nutty finish)
  • Grain or pasta (such as farro, quinoa, rice, barley, bowtie, couscous, penne) as the foundation

Notes:

  • Always use fresh, high-quality ingredients whenever possible!
  • If you’re in a pinch, you can substitute the wine with vegetable broth for a non-alcoholic version.
  • The vegan heavy cream can be made by soaking cashews in water, blending them until smooth, and adjusting with almond milk for the desired consistency.

Step-by-Step Instructions

  1. Preheat your oven to 350 degrees F (175 degrees C). Get that oven warming up so the gratin can bubble to perfection!

  2. Start the aromatic base: Heat the olive oil in a pan over medium heat. Add the diced onion, and sauté for 3 to 4 minutes until translucent and fragrant.

  3. Add the mushrooms: Toss in the sliced or quartered mushrooms, cooking them for an additional 5 minutes until they’re browned and tender.

  4. Deglaze with white wine: Pour in the white wine, letting it boil for a couple of minutes. This step lifts all those beautiful flavors stuck to the pan.

  5. Incorporate the kale: Add in the chopped kale and cook until just soft, about 4 minutes. The kale should be wilted and vibrant green.

  6. Create the creamy mixture: Stir in the vegan cream and almond milk. Let it simmer for several minutes, seasoning with Himalayan salt and cracked pepper to taste.

  7. Transfer to the baking dish: Pour the mixture into a baking dish, evenly spreading everything out.

  8. Bake: Place the dish in the oven and bake for about 25 minutes, or until the top is golden and bubbly.

  9. Serving time: Serve the gratin over a bed of your chosen grain or pasta, topped with a sprinkle of almond Parmesan for an extra touch of flavor.

Chef’s Tips:

  • Keep an eye on the baking time; ovens vary, and you want the gratin to be piping hot and golden brown.
  • For a crispy topping, broil the gratin for the last 2-3 minutes, keeping a close watch to avoid burning.

Common Mistakes to Avoid:

  • Don’t skip the deglazing step; it’s crucial for building depth of flavor.
  • Don’t overcook the kale during sautéing; you want it tender but still vibrant.

Expert Tips & Tricks

  1. Storage Recommendations: Leftovers can be stored in an airtight container in the fridge for up to 3 days. Just reheating in the microwave or the oven brings back its delightful flavors!

  2. Make-Ahead Instructions: Prepare the gratin up to the baking step and simply cover it tightly. When you’re ready to dive in, bake it straight from the fridge, adding a few extra minutes to the baking time.

  3. Troubleshooting Common Problems:

    • If your gratin is too watery, cook it uncovered for the last few minutes to allow extra moisture to escape.
    • For a creamier result, use a higher fat vegan cream.
  4. Balancing Flavors: If you want a little zing, consider adding a splash of lemon juice or a sprinkle of nutritional yeast to enhance the umami flavor.

  5. Experiment with Spices: Toss in some thyme or rosemary for an aromatic twist or a pinch of nutmeg for warmth.


Serving Suggestions

Pair your Kale and Mushroom Gratin with a simple side salad drizzled with lemon vinaigrette to cut through the richness of the dish. A glass of chilled white wine complements the meal beautifully. For an upscale presentation, serve in individual ramekins for individual servings. This gratin is perfect for cozy family dinners or intimate gatherings with friends.
