🧂 Gather Your Ingredients
- diced tomatoes - I like to use canned to cut down on prep.
- green chilies - provide a pop of flavor and a little bit of heat.
- pepper and onion strips - you can slice fresh veggies if you prefer, but the frozen pepper and onion strips have saved my life on many occasions!

Combine Ingredients
Add all of the ingredients to your slow cooker and mix well.
Cook
Cook on low for 3 to 4 hours, then serve over rice or on tortillas.
💡 Expert Tips and Tricks
- Be sure to drain all of the canned ingredients to avoid excess moisture in the slow cooker.
- If your tortillas fall apart or are stiff, heat them up in a skillet, in the microwave wrapped in lightly damp paper towels, or even directly over the flame of your stovetop (just be careful!).
❔ FAQs
There are certain vegetables like peas and asparagus that will get really mushy in the slow cooker, so I wouldn't recommend slow cooking them. Peppers can also get a bit mushy, but this recipe only cooks them long enough so they're tender and delicious!
You may have had some extra moisture in the slow cooker, or you just cooked them too long! Check at the 3 hour mark to see if everything is done to prevent cooking longer than needed.
My go-to seasonings for veggie fajitas are cumin, oregano, chili powder, and garlic. You can also throw in some smoked paprika, red pepper flakes, black pepper, onion powder, and ground coriander.
📝 Substitutions and Variations
- For even more veggie goodness, add zucchini or mushrooms to the mix.
- Give this dish some added protein with corn and/or black beans.
- Any kind of tortillas work well with this dish, so feel free to use a whole wheat or low-carb version to keep things lighter.
- Add a pop of refreshing flavor by squeezing some fresh lime juice over the fajitas before serving.
Kristin’s Kitchen Tip
If you want to use fresh veggies, slice and prepare everything the night before to save time during prep!
🥡 Storage and Reheating
If you have leftover slow cooker veggie fajitas, transfer to an airtight container and store in the fridge for 3 to 4 days. You can also freeze for 2 months or so.
Reheat in a skillet over medium heat or pop in the microwave and cook in 30-second increments. From frozen, allow the fajitas to thaw in the fridge and then reheat as normal.
⏳ Make Ahead Instructions
Prep for this recipe only takes a couple of minutes, but if you want to use fresh veggies instead of canned and frozen, do all of your chopping and dicing up to a day or so ahead of time and store in the fridge until it's time to slow cook.
