Fajita veggies

Want to make fajitas? Here are the best ever Fajita Veggies to go with any protein! Whether you’re making chicken, steak, shrimp, or veggie fajitas: you gotta have those signature sizzling veggies. This recipe makes the most tender, melt-in-your-mouth bell peppers, delicious savory onions, and meaty portobello mushrooms. Here’s what you’ll need, and how to do it!

Ingredients for the best fajita veggies

What do you need for fajita veggies? The list is simple and filled with good-for-you ingredients. Here’s what you’ll need:

  • 3 bell peppers: We like using red, yellow and green for maximum color contrast. Orange bell peppers also have great flavor.
  • 1 red onion: When it comes to onion, we opt for red onion for fajitas: it has a mellow flavor when cooked, and adds a lovely purple color.
  • 2 portobello mushroom caps: They’re optional, but portobello mushrooms add big meaty flavor (especially if you’re making vegetarian fajitas).

Seasoning for fajita veggies

You don’t need to go out and buy packets of fajita seasoning for these veggies! Nope, just a few spices you might already have on hand do the trick. But if you happen to have it, fajita seasoning works too. Here’s what to use to season these tasty veggies:

  • Cumin
  • Chili powder
  • Garlic powder
  • Smoked paprika: Smoked paprika is also labeled as pimentón at the grocery store. It has a very smoky flavor and is worth seeking out (you can also use it for these smoked paprika recipes).
  • Salt and pepper

Or, use homemade or purchased fajita seasoning!

Want to use fajita seasoning instead? You can do that too! Here’s what to know:

  • Try this Homemade Fajita Seasoning, or whatever purchased seasoning mix you have on hand.
  • Use 2 tablespoons seasoning instead of the spices listed below.
  • Important: most fajita seasoning has salt, so you’ll want to us less than the recipe specifies. Start with 3/4 to 1 teaspoon kosher salt and add more to taste.

Bell peppers nutrition

One great thing about these fajita veggies: they’ve got lots of bell peppers, which are loaded with a massive amount of Vitamin C! In fact, bell peppers have much more Vitamin C than oranges, though citrus usually gets the most credit for this nutrient. Here are some nutrition facts about bell peppers that make us fajitas even more:

  • Peppers are loaded with Vitamin C. A medium red bell pepper provides a whopping 169% of your daily vitamin C! (Source) So one serving of these fajita veggies provides 126% of your daily needs, since the recipe uses 3 bell peppers.
  • Peppers may improve eye health and prevent against anemia. Some studies indicate peppers could cut the risk of macular degeneration and low iron (Source).
