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
Using 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 ¾ to 1 teaspoon kosher salt and add more to taste.
How to make them into fajitas
Once you’ve got your fajita veggies…how to make them into actual fajitas? Perhaps you already have a favorite recipe. But if you’re looking for inspiration, we’ve got some ideas:
- Make chicken, steak, or shrimp fajitas by cooking 1 pound of meat with this Fajita Sauce. Alternatively, try our Shrimp Fajitas or use the grilled chicken recipe in our Fajita Salad.
- Make Vegetarian Fajitas with pinto beans (and the same sauce).
- Add the fajita veggies and tortillas.
- Load up on toppings: Sour cream, guacamole, hot sauce, and cilantro are must-haves in our house.

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).

I’ve made this a few times now, but this time I got the Sazon seasoning. Turned out very good. The pork is seasoned when finished and could be used for a bbq pulled pork sandwich or with fajita veggies for tacos. Used my crock pot. Four hours on high, then four on low. I put salta pepper on first, then the Sazon which also has salt, but considering your only putting it on the surfaces, it can handle the salt.
Made this last night for my book group and served it with shredded chicken. It was a bigger hit than the book!
Made these in our cast iron skillet for a football tailgate at our house! They were fantastic!!
Apologies I didn’t see the link on the words! Thanks for a fantastic recipe.
