Make It Now:

1. Make the Marinade: Add all of the marinade ingredients to a gallon-sized freezer bag. Use your hands to massage the bag from the bottom and combine the marinade. Then, add the steak, seal, and toss until the meat is evenly coated. (Freezing instructions begin here.) 

2. Marinate the Steak: Place the steak bag in the refrigerator to marinate for at least 1 hour and up to 24 hours, turning and/or massaging occasionally.

3. Stir Fry the Veggies: In a large skillet, heat 2 tablespoons oil over medium-high heat until shimmery. Carefully add the peppers and onions to the hot pan and saute until softened and charred, 5-7 minutes for fresh veggies or 7-9 minutes for frozen veggies. Season lightly with salt and pepper and the sugar (a key ingredient!) as they cook. Remove to a platter.

4. Stir Fry the Steak: Add 1 tablespoon of oil to the pan. Once it’s shimmery, saute the steak in two batches until brown on all sides, about 3 minutes per batch. Remove to the serving platter with the veggies.

5. Serve: Squeeze half a lime over all the meat and veggies. Top with chopped cilantro, if desired. Warm the tortillas according to package directions. Serve the meat and veggies on the tortillas with lime wedges and your favorite Tex-Mex toppings.


Freeze For Later: Freeze the marinated steak bag, alongside frozen peppers and onions. Two options for the frozen peppers and onions: 1) Buy a 20-22 ounce bag of frozen sliced peppers and onions, or 2) line up the fresh onion and pepper slices in a single layer on a sheet pan. Place in the freezer until solid and then toss the frozen veggies in a freezer bag. You can also freeze flour tortillas (not corn or gluten-free tortillas, though), along with this meal kit.

Prepare From Frozen: Thaw the bag of steak marinade using one of these safe methods, but do NOT thaw the peppers and onions. Follow Steps 3-5 in the recipe.


*Don’t hesitate to ask your butcher to slice the meat for the fajitas to save you time!

**Shortcut: Replace with 20-22 ounces of frozen pepper and onion blend from the freezer section.

What’s the Heat Level of This Recipe? Overall this recipe isn’t very spicy at all, so all ages can enjoy these. If you’d like more heat, simply add in more red pepper flakes to the marinade.

Where We Get Our Meat: We get our meat from ButcherBox. The chicken is organic and curated from small, trusted farms. The steak is grass-fed and grass-finished. Read about how this service works and our honest review here.
