Easy, Delicious Make-Ahead Fajitas

These chicken fajitas are wonderful straight from the sizzling skillet or made ahead and frozen for a quick, satisfying meal. Below you’ll find a straightforward step-by-step method for standard family-sized fajitas and a separate make-ahead version designed to feed a large crowd. Both yield tender, flavorful chicken and perfectly seasoned peppers and onions. Make them ahead, freeze, or serve immediately — either way, enjoy!

Step-by-step walkthrough

In a large bowl, whisk together all marinade ingredients and set aside.

Prep the chicken

Butterfly the chicken breasts so each piece is about ½ inch thick to promote even cooking.

Divide chicken into one or more 1-gallon freezer bags. Add approximately one-third of the marinade to the bag(s) with the chicken, reserving the remaining two-thirds for the vegetables. Seal bags, pressing out excess air, and refrigerate for 1 to 3 hours.

Prepare the vegetables

Slice onions and peppers into ½ inch strips and place in a large bowl. Pour the reserved marinade over the vegetables and toss to coat. Divide the vegetables into 1-gallon freezer bags if desired, press out air, and refrigerate until ready to cook. The reserved marinade acts mainly as seasoning for the veggies.

Cooking

When ready to cook, heat 2 tablespoons canola oil in a large, heavy skillet (cast iron preferred) over medium-high heat until smoking. Add enough chicken for a single layer and cook 8–10 minutes, turning every couple minutes, until golden brown and cooked through. Chicken is done when the thickest part reaches 150–160°F. Remove cooked chicken to plates and continue in batches until finished.

After the chicken is cooked, sauté the vegetables in the same skillet (in batches if needed) until they are softened and beginning to caramelize.

Finish and serve

Slice the cooled chicken diagonally into roughly ¼” × 2″ strips while the vegetables cook. If serving immediately, return the chicken and any accumulated juices to the skillet with the vegetables and heat briefly until warmed through. Wrap tortillas in a damp cloth and microwave in 30-second intervals until hot. Serve with warm tortillas, sour cream, shredded cheese, tomatoes, and shredded lettuce.

Note: If not serving immediately, cool the chicken and vegetables and divide into freezer bags. Pour any collected chicken juices over the chicken in the bags to keep it moist. Refrigerate up to 2 days or freeze up to 4 months.

Reheating and serving from frozen

If frozen, thaw overnight in the refrigerator. One hour before serving, preheat the oven to 325°F. Combine chicken and vegetables in roasting trays, cover tightly with foil, and rewarm for 45–60 minutes (convection ovens may be faster). About 20 minutes before serving, wrap tortillas in foil in batches of 10–15 and warm in the oven for about 10 minutes. Keep wrapped until serving.

Family-size Make Ahead Chicken Fajitas

Make Ahead Chicken Fajitas for a Large Group

When cooking for many people, do the heavy prep well in advance. This method keeps the chicken moist, captures great flavor from high-heat cooking, and makes serving a crowd simple.

Large-group plan

1. Up to 4 months ahead: prepare chicken and vegetables and freeze in meal-sized bags.
2. Day before: thaw in the refrigerator.
3. Up to 4 hours before serving (no later than 1 hour 15 minutes): Preheat oven to 325°F. Combine chicken and vegetables in large roasting pans, cover tightly with foil, and rewarm 45–60 minutes. Keep tortillas wrapped until serving.

Optionally hold in slow cookers on low for up to 2 hours once warmed. Serve with warm tortillas, sour cream, tomatoes, and lettuce.
