3 cups cooked quinoa

1 small shallot, minced

34 cloves garlic, minced

1 sprig fresh rosemary, chopped

3 sprigs fresh thyme

23 fresh sage leaves, chiffonaded

Salt and pepper, to taste

Juice of 1/2 lemon

4 cloves garlic

1 tsp salt

1/2 tsp white miso paste (optional)

Shredded vegan cheese

Instructions

  1. Blend all cream sauce ingredients in a high-speed blender until smooth. Adjust seasoning as needed and set aside.

  6. Bake 20–25 minutes, until the top is lightly golden. Serve hot.

Notes

Make nut-free by using sunflower seeds or a tofu-based sauce.

Add spinach, kale, or zucchini for more vegetables.

For a heartier bake, stir in cooked lentils or chickpeas before baking.

Enhance flavor with smoked paprika or a splash of tamari in the sauce.

Freeze baked dish up to 2 months; thaw overnight before reheating.
