A grilled fajita seasoning recipe should taste like Texas fajitas—zesty, smoky, and cumin-forward—without a long marinade list. Season skirt steak with a fajita rub, grill hot and fast, slice against the grain, and pile it with charred peppers and onions.
This skirt steak fajitas grilled method is built for a backyard cookout: dry the steak, coat with Lone Star - Fajita (https://battlefieldblends.com/headquarters/p/product-1-ydar7-e8mlb-r2y28-swt2t-pnt6l-8sxgn-ky2xz-5ytes-w4lxk), sear over high heat, then rest and slice. Soft tortillas and the usual toppings finish the plate.
**Yield:** 4–6 servings (about 1½–2 lbs skirt steak)
**Prep:** 20 minutes (+ optional 30–60 min fridge rest after seasoning)
**Cook:** 10–15 minutes (steak + veggies)
**Total:** about 35–75 minutes depending on rest
**Food safety:** Beef steaks should reach **145°F** internal and rest **at least 3 minutes** (USDA). Fajitas are often sliced closer to medium; see the temperature guidance below so you hit a safe cook and the doneness you want.

## Why This Recipe Works
Texas fajitas on the grill come down to cut choice, heat, and slicing—not a complicated sauce.
1. **Skirt steak (or a close substitute).** Thin, well-marbled, and made for high heat. Outside skirt is often preferred when you can find it; inside skirt works with the same method.
2. **Dry surface + fajita rub.** Pat the steak dry so the seasoning sticks. A homemade fajita seasoning lane is already in the jar—no need to invent a long spice list.
3. **Hot and fast, then rest.** Sear over high direct heat for a crust, pull to temp, and rest before slicing so juices stay in the meat.
4. **Slice against the grain.** Skirt has long muscle fibers. Cutting across them is what keeps grilled fajitas tender.
5. **Clear steak temp guidance.** USDA safe minimum for steaks is **145°F + 3-minute rest**. Many fajita cooks prefer medium (~140–145°F before rest, finishing near medium after carryover). Treat **145°F + rest** as the food-safety floor for steaks; if you prefer rarer, that is a personal choice outside USDA guidance—never serve undercooked steak to high-risk guests.
## Battlefield Blends Product Used
**Lone Star - Fajita (https://battlefieldblends.com/headquarters/p/product-1-ydar7-e8mlb-r2y28-swt2t-pnt6l-8sxgn-ky2xz-5ytes-w4lxk)** ($12) — zesty and smoky fajita rub with **heat: mild**. Flavor briefing: smoky, zesty, savory (savory & zesty). Best on beef, chicken, and veggies per the Flavor Briefing (https://battlefieldblends.com/flavor-briefing).
From the official product page: *“A zesty and smoky rub with paprika fire and cumin edge—field-tested for fajitas, tacos, and grilled meats.”* Tagline: *ZESTY. SMOKY. TEXAS-BRED.* The page describes smoky paprika, fiery chiles, and a cumin-driven edge for sizzling fajitas, tacos, and grilled meats.
Seasoning amounts below are a practical starting point for skirt steak and fajita veggies—adjust to taste. Lone Star already brings salt and mild heat; taste before adding extra salt or chile.
## Ingredients
**Steak**
- 1½–2 lbs skirt steak (outside or inside), trimmed of excess silver skin
- 1–1½ Tbsp neutral oil (avocado, canola, or similar)—just enough to help the rub cling
- 2–3 Tbsp **Lone Star - Fajita** (about 1–1½ Tbsp per pound; start light, add more for a heavier crust)
- Juice of ½ lime, optional (brush on after grilling, not as a long marinade)
- Kosher salt only if needed after tasting the rub
**Fajita veggies**
- 2–3 bell peppers (mixed colors), sliced into strips
- 1 large yellow or white onion, sliced into strips
- 1–2 Tbsp neutral oil
- 1–1½ Tbsp **Lone Star - Fajita**
- Optional: 1 jalapeño, sliced (extra heat beyond the mild rub)
**To serve**
- Warm flour or corn tortillas
- Lime wedges
- Cilantro, pico de gallo, guacamole, sour cream, or shredded cheese as you like
- Extra pinch of Lone Star at the table
## Equipment
- Gas, charcoal, or pellet grill capable of **high direct heat** (cast-iron griddle or plancha optional for veggies)
- Instant-read thermometer
- Sharp knife and cutting board for slicing against the grain
- Tongs, sheet pan, and a clean platter for resting
- Clean, oiled grates
**No grill?** See Variations for cast-iron and broiler notes.
## Prep
1. **Trim and dry the steak.** Remove thick silver skin. Pat the skirt steak bone-dry with paper towels—moisture fights browning.
2. **Season the steak.** Lightly oil both sides. Coat evenly with Lone Star - Fajita. You want a visible, even crust, not bare patches.
3. **Optional rest:** Refrigerate seasoned steak uncovered or loosely covered 30–60 minutes (or up to a few hours). Pull out about 20 minutes before grilling so it isn’t ice-cold.
4. **Prep veggies.** Slice peppers and onion into even strips. Toss with oil and Lone Star so they’re coated but not pasty.
5. **Preheat the grill** for high direct heat (lid closed until the grate is hot). Clean and oil the grates.
## Step-by-Step Instructions (Hot Grill)
**Grill setup**
- **Direct zone:** high heat for the steak (you want a fast sear)
- **Optional cooler zone:** for holding veggies or finishing if flare-ups spike
**Charcoal:** Build a hot bed; leave a cooler edge.
**Gas:** High burners under the sear zone.
**Pellet:** Run as hot as your grill allows for searing, or use a cast-iron insert / open-flame sear if available.
1. **Grill the veggies first or alongside.** On a hot grate, basket, or cast-iron plancha, cook peppers and onions until softened with charred edges, 8–12 minutes, tossing occasionally. Move to a warm platter and tent loosely.
2. **Sear the skirt steak** over high direct heat. Grill about **3–5 minutes per side** depending on thickness, flipping once (or twice if you need to manage flare-ups). Skirt is thin—don’t walk away.
3. **Check temp.** Probe the thickest section. For USDA steak guidance, cook to **145°F** and rest **at least 3 minutes**. Many home cooks pull skirt closer to **135–140°F** for medium-rare after carryover; that is below the USDA steak minimum—use **145°F + rest** when you want clear food-safety alignment, especially for guests.
4. **Rest the steak** on a clean board or platter, tented loosely, **5–10 minutes** (include the USDA 3-minute rest inside this window if you cooked to 145°F).
5. **Slice against the grain.** Find the direction of the long fibers and cut perpendicular into thin strips. If the skirt is very long, cut it into manageable sections first, then slice each section against the grain.
6. **Finish and serve.** Toss sliced steak with a squeeze of lime if using. Warm tortillas on the grill 15–30 seconds per side. Build fajitas with steak, peppers, onions, and toppings. Dust with a pinch more Lone Star if you want extra fajita seasoning at the table.
**Doneness cues:** Thermometer in the thickest meat; rested juices; deep browned crust without a burnt spice shell; veggies soft with charred edges.

## Serving Suggestions
Serve family-style: platter of sliced steak, platter of peppers and onions, stack of warm tortillas, and toppings in the middle of the table.
**Easy sides:** cilantro-lime rice, black beans, grilled corn, simple slaw, or chips and salsa. For a dual-protein cookout, add a platter of honey BBQ chicken wings (https://battlefieldblends.com/mission-recipes/honey-bbq-chicken-wings-grilled) so not everything on the table is beef.

## Variations
**Chicken fajitas**
Use the same Lone Star coating on boneless chicken thighs or breasts. Grill until the thickest meat reaches **165°F** (USDA poultry). Slice and serve with the same veggies and tortillas.
**Flank or hanger instead of skirt**
Same method; thicker cuts need a little more time—trust the thermometer and still slice against the grain.
**Milder plate**
Lone Star is mild heat. Skip the jalapeño and keep dairy toppings on the side for heat-sensitive eaters.
**More char, less spice crust burn**
If the rub is darkening too fast, sear slightly cooler or flip more often. Sugar/chile in fajita blends can scorch on ripping-hot grates.
**Cast-iron (stovetop)**
Preheat a large cast-iron skillet until very hot. Sear steak 3–5 minutes per side to temp, rest, slice. Cook veggies in the same pan after wiping excess fat.
**Broiler**
Position rack ~4–6 inches from the element. Broil steak on a foil-lined sheet, flipping once, until you hit your target temp. Watch closely—broilers vary.
**Make-ahead**
Season steak up to several hours ahead. Slice only after cooking and resting. Leftover sliced fajita steak reheats best in a hot skillet for 1–2 minutes—don’t boil it in a microwave puddle.
## Storage & Reheating
- **Fridge:** Sliced steak and veggies in airtight containers, up to 3–4 days.
- **Freeze:** Cooked sliced steak up to 2 months; thaw overnight in the fridge.
- **Reheat:** Hot skillet with a splash of oil or broth, 1–3 minutes until just warm. Overheating toughens skirt.
- **Tortillas:** Warm fresh; don’t store assembled fajitas if you care about texture.
## FAQs
**What is a good grilled fajita seasoning recipe if I don’t want to mix spices from scratch?**
Use a dedicated fajita rub. Lone Star - Fajita (https://battlefieldblends.com/headquarters/p/product-1-ydar7-e8mlb-r2y28-swt2t-pnt6l-8sxgn-ky2xz-5ytes-w4lxk) is built for that lane—zesty, smoky, cumin-edged—so you season and grill instead of measuring a long spice list.
**What internal temperature for skirt steak fajitas?**
USDA guidance for beef steaks is **145°F** internal with a **3-minute rest**. Fajitas are often served sliced at medium; use a thermometer and choose the doneness that matches your risk tolerance. For poultry fajitas, cook chicken to **165°F**.
**Skirt steak vs flank for Texas fajitas?**
Both work grilled. Skirt is the classic fajita cut—thinner, beefier, and fast on high heat. Flank is a common substitute; still slice against the grain.
**Do I need a marinade?**
No. A dry fajita seasoning and high heat are enough. Optional lime after the grill adds brightness without watering down the crust.
**Is Lone Star spicy?**
Heat level is **mild**. You’ll get chile presence and cumin edge without a hot-rub burn. Add fresh jalapeño if you want more heat.
