Fajita Bowl Ingredients

All the ingredients mise en place for making vegetarian fajita bowls with spices, mushrooms, peppers, onions and black beans.

A complete list of ingredients with amounts and full instructions is located in the printable recipe card below. This section covers ingredient and substitution considerations.

  • Uncooked rice: Use any variety of rice such as basmati rice, jasmine rice or brown rice. Other grains like quinoa also work.
  • Portobello Mushrooms: The recipe calls for portobello mushrooms but if you can’t find any, you can use button mushrooms or cremini mushrooms.
  • Spices: This recipe calls for chili powder, cumin, cayenne powder, and smoked paprika. To adjust the heat, you can add a bit more cayenne pepper. You can also use packaged fajita seasoning.
  • Cilantro: If you don’t like cilantro, go ahead and omit it.
  • Soy sauce: You’ll need soy sauce to make the marinade for the mushrooms. For a gluten-free option, use tamari or coconut aminos.
  • Lime zest: You’ll need 1-2 limes to make enough zest, plus more for serving if desired.
  • Bell Pepper: You’ll need 3 bell peppers in varying colours (they don’t have to be different colours but it’s more fun!).
  • Onion: White onion, red onion or yellow onion is suitable.
  • Green Onion: Also known as scallions. An optional topping!
  • Black beans: Canned is fine for this recipe. Drain and rinse them before use.
  • Avocados: Optional for serving.
  • Toppings: Hot sauce and sour cream are optional but delicious toppings for your fajita bowls.
  • Olive Oil: You’ll need a bit of oil for the marinade and the veggies. You can use a different vegetable or cooking oil if you like.
  • Balsamic Vinegar: Additional seasoning for the mushroom marinade.

How to Make a Fajita Bowl

Step 1: Mix the Spices

Mix together all of your spices in a small bowl until well combined.

Step 2: Marinate the Mushrooms

Place ½ of the spice mixture in a large bowl with the soy sauce, balsamic vinegar, and 1 tbsp of olive oil. Mix thoroughly, removing any lumps.

Once everything is evenly mixed, add the sliced mushrooms. Coat them with the marinade, set them aside and allow them to marinate for 15 minutes.

Step 3: Cook the Rice

While the mushrooms are marinating, cook your rice according to package instructions, along with 1/2 tsp cumin.

Once the rice is finished cooking, fold in the lime zest. You can also mix in some finely chopped cilantro or save the cilantro for topping.

Step 4: Cook the Peppers & Onions

Cook the sliced peppers and onions in 2 tsp of olive oil, as well as the remainder of the spice mixture from earlier.

Cook them over medium heat in a large skillet or non-stick pan until soft, about 5-7 minutes.

Quick Tip: You could skip the oil here and just use a bit of water if you like.

Step 5: Broil the Mushrooms

Preheat the oven to broil (500 F).

When the peppers are almost ready, take the marinated mushrooms and lay them flat on a baking sheet. Place in the oven on broil for 2 minutes, remove from the oven and flip and broil for an additional 1 minute.

Step 6: Assemble your Fajita Bowls

When everything is cooked, you can start assembling your bowls! Evenly distribute each ingredient amongst 6 bowls.

Garnish with cilantro, green onions, and avocado. Serve with a dollop of sour cream or any other toppings you might enjoy.

Quick Tip: The recipe can make 4-6 bowls. If you’re making 6 bowls, increase the rice to 2 cups uncooked and include an extra avocado so you have half per bowl. Note that if you’re making these for meal prep to leave the avocado off until just before serving.

FAQs

Can I use packaged fajita seasoning?

Yes. To use prepared fajita seasoning, omit the garlic powder, smoked paprika, chili powder, cumin, onion powder and cayenne and use about 1 tbsp of fajita seasoning each for the mushrooms and vegetables.

Are fajita bowls gluten-free?

The recipe is nearly gluten-free as written, just make sure you use gluten-free tamari or coconut aminos instead of soy sauce.

Storing & Making Ahead

  • Chop the veggies and make the rice ahead of time for quicker assembly.
  • Assembled bowls (without the avocado) will keep in the fridge for 3-4 days.
  • Reheat in the microwave until heated through, add avocado and other toppings and enjoy.
