Prepration for:Gluten-Free, Soy-Free, Dairy-Free Creamy Broccoli Casserole

Step 1/4

Cook Pasta and Broccoli

Bring a large pot of water to a boil. Add gluten-free pasta and cook until al dente (check package). Add broccoli florets to the pot for the last 3–4 minutes of cooking. Drain and set aside.

Step 2/4

Make Cream Sauce

In a blender, combine soaked cashews, plant milk, nutritional yeast, lemon juice, garlic powder, onion powder, salt, and pepper. Blend until smooth. In a saucepan over medium heat, add olive oil and gluten-free flour. Stir to create a roux. Slowly whisk in the blended cashew mixture until thickened, about 3–5 minutes.

Step 3/4

Assemble

Preheat oven to 180°C (350°F). In a large mixing bowl, combine the pasta, broccoli, and creamy sauce. Transfer to a greased 9×13″ casserole dish (or disposable foil tray as seen in the image). Sprinkle dairy-free cheese and/or gluten-free breadcrumbs on top.

Step 4/4

Bake

Cover with foil and bake for 20 minutes. Uncover and bake for another 15–20 minutes until bubbly and golden on top.

Chef's Tips & Notes

Tips: For added protein, toss in chickpeas or cooked lentils. Use pre-cut frozen broccoli to save time. Want extra richness? Add a spoonful of dairy-free cream cheese to the sauce.
