Enchilada Quinoa Bake
A hearty Tex-Mex inspired quinoa and sweet potato casserole that bakes in one pan and slices cleanly for grab-and-go lunches. Ideal for busy families and vegetarian meal preppers, it stays fresh up to 5 days in the fridge and freezes well for up to 3 months. Perfect for make-ahead dinners or office-friendly lunches that reheat beautifully.
Equipment
- 9x13 baking pan
- 8x8 baking pan (optional for thicker portions)
- Aluminum foil
- Cutting board
- Chef's knife
- Large mixing spoon
- Measuring cups and spoons
- Fine-mesh strainer (for rinsing quinoa)
- Oven
Ingredients
- as needed nonstick cooking spray or olive oil for greasing pan
- 1 cup white quinoa, uncooked thoroughly rinsed and drained
- 2 cups vegetable stock or water
- 1 1/2 pounds sweet potatoes about 2 medium (roughly 5 cups), cut into bite-sized chunks
- 1 red bell pepper chopped
- 1 small yellow onion thinly sliced
- 2 tablespoons olive oil
- 1 teaspoon ground cumin
- 1/2 teaspoon garlic powder
- 3 teaspoons chili powder divided
- 1 can (15 oz) fire-roasted corn drained
- 1 can (15 oz) black beans rinsed and drained
- 1 can (10 oz) mild red enchilada sauce
- 2 tablespoons lime juice freshly squeezed
- 1/4 cup fresh cilantro chopped
- 1 1/2 cups sharp cheddar cheese divided; shredded Mexican blend works too
- salt to taste
- black pepper to taste
- toppings of choice avocado, plain Greek yogurt, hot sauce, extra cilantro, lime wedges; add after reheating
Instructions
- Preheat oven to 400°F. Lightly grease a 9x13 baking pan with a little olive oil or nonstick spray.
- Add sweet potato chunks to the pan. Drizzle with olive oil; sprinkle with cumin, garlic powder, and 2 teaspoons chili powder. Toss to coat and spread evenly. Roast for 15 minutes until edges begin to soften.
- Remove the pan from the oven. Add rinsed quinoa, vegetable stock, enchilada sauce, black beans, fire-roasted corn, diced bell pepper, sliced onion, lime juice, and remaining 1 teaspoon chili powder. Stir to combine. Season with salt and black pepper to taste.
- Cover tightly with foil to trap steam and bake for 30 minutes.
- Remove foil and stir. Quinoa should be mostly cooked with a little liquid remaining. Stir in cilantro, then top with 1 cup of the shredded cheese. Sprinkle the remaining 1/2 cup over the top.
- Bake uncovered for 15 minutes, until cheese is golden and quinoa has absorbed remaining liquid.
- Cool completely on the counter before cutting so squares hold their shape.
- Cut into 6 even squares and portion into airtight meal prep containers. Label with the date.
Notes
- Storage: Refrigerate in airtight containers for up to 5 days. Do not leave at room temperature for more than 2 hours after baking.
- Freezer-friendly: Cool completely, cut into squares, wrap each square individually, and place in a freezer-safe bag or container. Freeze up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheating: For single portions, microwave covered with a damp paper towel on medium power for 90 seconds, stir, then heat another 30–60 seconds. For multiple portions, cover with foil and reheat in a 350°F oven for about 15 minutes.
- Meal prep timing: Bake on Sunday, cool fully before slicing, then portion. A 9x13 pan yields 6 portions; an 8x8 pan yields 4 thicker portions.
- Add protein: Stir in about 1 lb cooked, shredded rotisserie chicken at the mixing step before baking (no change to bake time).
- Vegetarian boost: For extra plant protein, add an additional can of black beans (skip pinto beans if storing for 5 days as their texture can turn grainy).
- Serving ideas: Add toppings after reheating—sliced avocado, plain Greek yogurt or sour cream, hot sauce, extra cilantro, or a squeeze of lime.
- Tip for clean slices: Cooling fully is essential; warm casserole will crumble when cut.
