Ingredients

• 6 cups yellow squash
• 2 tablespoons olive oil
• 1 medium, chopped yellow onion
• 3 cloves, minced garlic
• 1 cup dairy-free mayonnaise
• 1 cup dairy-free shredded cheese
• 2 tablespoons nutritional yeast
• 1 cup gluten-free breadcrumbs
• 2 tablespoons chopped fresh parsley
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 0.5 teaspoon paprika

Directions

Step 1

Preheat your oven to 350°F (175°C).

Step 2

Slice the yellow squash into 1/4-inch rounds. Steam them for about 5-7 minutes until just tender. Drain and set aside.

Step 3

In a medium skillet over medium heat, heat the olive oil. Add the chopped onion and cook until translucent, about 5 minutes.

Step 4

Add minced garlic to the skillet, stir and cook for another 1-2 minutes until fragrant.

Step 5

In a large mixing bowl, combine the steamed squash, sautéed onion and garlic, dairy-free mayonnaise, dairy-free shredded cheese, nutritional yeast, salt, black pepper, and paprika. Mix gently until everything is well distributed.

Step 6

Transfer the mixture into a lightly greased 9x13 inch baking dish, spreading it evenly.

Step 7

In a separate small bowl, mix the gluten-free breadcrumbs with chopped parsley.

Step 8

Sprinkle the breadcrumb mixture evenly over the squash mixture in the baking dish.

Step 9

Bake in the preheated oven for 30 minutes until the top is golden and crispy. If preferred, broil for an additional 2-3 minutes to achieve a deeper golden crust.

Step 10

Remove from the oven and let it cool for a few minutes before serving.
