Cook’s Kit

Before you start, make sure you have the following kitchen tools on hand:

• Large baking sheet—this is where all the magic happens!
• Sharp knife—perfect for slicing vegetables and mushrooms.

Step-by-Step: Sheet Pan Portobello Mushroom Fajitas

Step 1: Preheat Your Oven

Begin by preheating your oven to 425°F (220°C). This high temperature will help caramelize the vegetables and mushrooms, enhancing their natural flavors.

Step 2: Prepare Your Vegetables

Slice the red onion into thin wedges and the bell peppers into strips. For the portobello mushrooms, remove the stems and cut them into thick slices. Set aside.

Step 3: Create the Spice Mix

In a small bowl, combine the fajitas spice mix ingredients: sweet smoked paprika, ground cumin, garlic powder, oregano, salt, pepper, and hot chili powder or flakes. Mix well and set aside.

Step 4: Toss the Veggies

On a large baking sheet, spread out the sliced onion, bell peppers, and portobello mushrooms. Drizzle with olive oil and sprinkle the spice mix over the top. Use a spatula to toss everything together, ensuring the veggies are well-coated.

Step 5: Roast the Fajitas

Place the baking sheet in the preheated oven. Roast for 20-25 minutes, stirring halfway through, until the vegetables are tender and slightly charred.

Step 6: Warm the Tortillas

While the veggies are roasting, warm your tortillas. You can do this in a dry skillet over low heat for about 30 seconds on each side or wrap them in foil and place them in the oven for the last 5-10 minutes of roasting.

Step 7: Assemble Your Fajitas

Once the veggies are ready, remove them from the oven. To assemble, place a generous amount of the roasted mixture onto each tortilla. Top with guacamole, salsa, sour cream, and black beans.

Step 8: Serve and Enjoy

Serve your Sheet Pan Portobello Mushroom Fajitas hot, garnished with extra toppings of your choice. Enjoy with friends or family for a fun, interactive meal!
