Ingredients

Cooked quinoa – Prepping it in advance (like in an Instant Pot) makes weeknight dinner prep much easier.
Marinara sauce – Choose a dairy-free brand by checking labels carefully.
Tomato paste – For added richness.
Vegan heavy whipping cream – Any brand is fine. This gives it that creamy texture.
Garlic – Because everything is better with garlic!
Vegan mozzarella shreds – Melty, cheesy goodness.
Grape tomatoes (halved) – Juicy and sweet.
Basil (fresh or dried) – Fresh adds the best flavor.
Salt & pepper – To taste.

Instructions

This recipe is super simple and comes together in no time! Here’s how to make it:

Step 1: Cook the Quinoa and Preheat Oven to 350° F

If you haven’t prepped your quinoa yet, now’s the time! My go-to method is the Instant Pot:

Lightly spray the Instant Pot liner with cooking oil.
Add 2 cups of rinsed quinoa and 3 cups of water with a pinch of salt.
Set to manual pressure cook for 3 minutes.
Once done, let it sit for 10 minutes before carefully releasing any remaining pressure.

Step 2: Make the sauce

While the quinoa is cooking, grab a large saucepan and heat:

Marinara sauce and tomato paste over medium heat.
Once warmed, stir in vegan heavy whipping cream, garlic, chopped basil (fresh or dried), salt, and pepper.

Step 3: Combine everything

Remove the sauce from heat and fold in the vegan mozzarella shreds along with all of the cooked quinoa.

Step 4: Assemble and bake

Lightly spray a 9×13 baking dish with a little cooking spray to keep everything from sticking.

Next, pour in your delicious quinoa mixture and spread it out nice and evenly.

Sprinkle some extra vegan mozzarella shreds over the top, then add a handful of halved grape tomatoes for a pop of color and flavor.

Pop it in the oven and bake at 350°F for about 15 minutes, until it’s warm, melty, and just a little golden around the edges.

Step 5: Serve and enjoy!

Lastly, sprinkle with a little more fresh or dried basil for garnish as well as a few more halved cherry tomatoes if you wish.
Now grab a plate and enjoy this warm, cheesy, and delicious dish!

Storage

Refrigeration:

Be sure to let the casserole cool completely before storing.
Transfer leftovers to an airtight container or cover the baking dish tightly with foil or plastic wrap.
This will store in the refrigerator for up to 4 days.

Freezing:

For longer storage, place cooled casserole in a freezer-safe container or wrap it tightly in plastic wrap and then foil.
It can be frozen for up to 3 months.

Reheating Instructions:

From the fridge: Reheat individual portions in the microwave for 1–2 minutes or warm the entire casserole in a 350°F oven for 15–20 minutes.
From frozen: Thaw overnight in the fridge, then reheat as above. If reheating straight from frozen, bake at 350°F for 30–35 minutes, covered with foil to prevent drying out.
