Overview
Chicken fajitas feature marinated, grilled chicken served with sautéed bell peppers and onions. Sous vide eliminates the risk of dry chicken breast while infusing the meat with classic fajita flavors. A quick sear after the bath adds char and texture that mimics traditional grilling.
Core Time & Temperature
| Doneness | Temperature | Time | Max Time |
|---|---|---|---|
| Juicy | 145°–150°F | 2–4 h | 6 h |
| Tender | 155°–160°F | 2–4 h | 6 h |
Cooking time depends on thickness, not weight. Measure at the thickest part.
Food Safety Notes
Chicken should reach at least 165°F / 74°C for immediate consumption per USDA guidelines. However, pasteurization can be achieved at lower temperatures with sufficient time. Cooking at 145°F for 2+ hours or 155°F for 1.5+ hours achieves equivalent safety. Hold the bath long enough to achieve full pasteurization (see time table). Finish with a high-heat sear to prevent cross-contamination.

Texture Profiles
- 145°–150°FJuicy
- Ultra-moist chicken with a slight give. This is as juicy as chicken breast gets - tender, succulent, and perfect for those who hate dry chicken.
- 155°–160°FTender
- Traditional chicken breast texture with good moisture. Firmer than the juicy profile but still tender - closer to what most people expect from grilled chicken.
Prep & Bagging
- Prepare fajita marinade with lime juice, garlic, chili powder, and cumin (Can also add jalapeños for heat)
- Marinate chicken breasts for 1–4 h in refrigerator (Longer marination = more flavor)
- Transfer chicken and 2–3 tbsp marinade to vacuum bag (Don't add too much liquid)
- Vacuum seal or use water displacement method
- Ensure chicken is fully submerged in water bath
Finishing & Searing
- Remove chicken from bag and pat completely dry
- Heat cast iron skillet over high heat
- Add small amount of oil
- Sear chicken for 1–2 min per side until golden
- Transfer to cutting board and rest 3–5 min
- Slice into strips against the grain
- Toss with sautéed peppers and onions
- Serve immediately in warm tortillas
