For a crowd-pleasing vegetarian dinner, try Roasted Root Vegetable Tacos topped with plant-based Sunflower Seed Queso sauce.
Every year around this time, our neighbor gifts us a bounty of fresh root vegetables from his garden. Russets, purple potatoes, beets, and carrots of all colors. All grown at 8,500 feet. It's pretty amazing.
Roasting was my (obvious) first choice when it came to how to eat them.
I love that roasting is relatively easy and hands-off, but the real benefit is the flavor (and color) that you get when you brown the surface of the food in a hot oven.
I usually set the temperature somewhere between 400-450º F when I'm roasting. The right temperature will depend on the size and type of food you're cooking, but you're looking for a result that's brown and crispy on the outside and tender on the inside. Delicious.
For hearty root veggies, like the potatoes, carrots, and beets I used for these tacos, I like to roast all the way up at 450º F. This makes the process as speedy as possible and supports maximum browning. (🙌)
Once roasted, these crispy and tender root vegetables are ideal for tacos.
Especially when they're topped with warm Sunflower Seed Queso sauce. So good.
How to Make Sunflower Seed Queso
Since you make it with sunflower seeds instead of the more commonly used cashews or almonds, this vegan queso is also great for anyone who has a nut allergy.
To make it:
First, you need to soak sunflower seeds in water for at least an hour. This helps soften the seeds and make the cheese sauce smooth and creamy. Use raw (not roasted and salted) sunflower seed kernels for this recipe.
Once the sunflower seeds are soaked, drain sunflower seeds from soaking liquid and transfer to a blender container.
Add soy milk (or any milk you have on hand), nutritional yeast (this provides the cheesy flavor), chipotle peppers in adobo sauce (don't rinse off the sauce!), onion powder, garlic powder, and salt.
Blend this mixture on high for about three minutes. You may need to pause to scrape the edges of the blender container with a spatula. Just keep blending until the mixture is smooth and creamy. If it's not mixing well, try adding a little more soy milk or water and blend again.
Once the queso is blended, heat the sauce in a saucepan over low-medium heat.
At this point, the queso sauce should be smooth and creamy, but it may be a little bit thicker than you'd like for drizzling over tacos.
Try whisking in a tablespoon of water. Repeat as needed until you reach your desired consistency for the sauce.
Keep the queso warm over the stovetop, stirring every few minutes and thinning with water as needed, until the root vegetables are ready.

Then drizzle the warm queso cheese sauce on top.
Finally, garnish with any of your favorite taco toppings. I like cilantro, green onions, jalapeño peppers, and lime wedges.
Can you make these root vegetable tacos ahead of time? What's the best way to store them?
I've been reheating leftovers nonstop, so this is definitely something you can make ahead of time if you want.
Store the roasted root vegetables and sunflower seed queso in separate airtight containers and refrigerate. Then wait to assemble with the tortillas and toppings until the day of.
A note on making the queso sauce in advance:
The Sunflower Seed Queso tends to thicken over time in the fridge. Just whisk in a tablespoon of water, or more, if needed, until you reach the right consistency. Before serving, reheat queso sauce on the stovetop or in the microwave.

To soak sunflower seeds: Cover the seeds in water, cover with a lid or clean towel, and allow to soak for at least one hour or overnight.
For gluten-free variation, use corn tortillas. Ensure chipotles in adobo and soy milk are gluten-free (most varieties are).
Making Ahead and Storage: Store root vegetables and queso in separate airtight containers and refrigerate up to a week. The Sunflower Seed Queso may thicken over time. To thin before serving, gradually add water and whisk until you reach the desired consistency.
