Make Roasted Cauliflower and Black Bean Sheet Pan Fajitas.: A Simple Method

Step 1: Preheat Your Oven
Preheat your oven to 425°F (220°C). This high temperature will help achieve that perfect roasted texture.
Step 2: Prepare the Vegetables
Cut the cauliflower into bite-sized florets, and slice the bell peppers and sweet onion into strips. Aim for similar sizes for even cooking.
Step 3: Whisk Together the Marinade
In a large mixing bowl, whisk together the olive oil, lime juice, lime zest, honey, cumin, chili powder, smoked paprika, salt, black pepper, and minced garlic. This mix will infuse the veggies with flavor.
Step 4: Combine the Ingredients
Add the cauliflower, bell peppers, and onion to the bowl with the marinade. Toss until everything is well coated. Allow it to marinate for about 10 minutes for maximum flavor.
Step 5: Roast the Vegetables
Spread the marinated veggies out evenly on a sheet pan. Roast for 20 minutes, stirring halfway through, until they are tender and lightly charred.
Step 6: Add the Black Beans
After the veggies have roasted, remove the pan from the oven and add the drained and rinsed black beans. Toss everything together and return it to the oven for an additional 5-10 minutes to heat through.
Step 7: Serve and Enjoy
Once everything is perfectly roasted, remove the pan from the oven. Serve the fajita mix in warm tortillas, topped with avocado slices, chopped cilantro, lime wedges, and a sprinkle of cotija cheese and sour cream if desired.

Slip-Ups to Skip
To ensure the best results with your Roasted Cauliflower and Black Bean Sheet Pan Fajitas, keep these tips in mind:
- Avoid overcrowding the pan; this can lead to steaming instead of roasting. Use two pans if necessary.
- Don’t forget to stir the veggies halfway through roasting to ensure even cooking.
- Make sure to drain and rinse the black beans properly to avoid excess sodium and unwanted canning liquid.
- Let the marinated vegetables sit for at least a few minutes to absorb the flavors before roasting.
Store, Freeze & Reheat
If you have leftovers (which is unlikely, but just in case!), here’s how to store them:
- Store in an airtight container in the refrigerator for up to 3 days.
- To freeze, place in a freezer-safe container for up to 2 months. Thaw in the refrigerator overnight before reheating.
- Reheat in the oven at 350°F (175°C) until warmed through, or microwave in short intervals until hot.
