Fajitas are a popular Tex-Mex dish made of grilled meat served on a warm tortilla. The most common types of meat used are skirt steak, chicken and shrimp. While fajita recipes call for specific cuts of meat, many people wonder where exactly these cuts come from on a cow. In this article, we will explore the origins of the three main fajita meats – skirt steak, chicken breast and shrimp – and identify their location on a cow or chicken.
What is Skirt Steak?
Skirt steak is considered one of the most popular cuts of beef used for fajitas. It comes from the diaphragm muscles of a cow, specifically the superficial muscles of the lower portion of the abdominal wall. These muscles support breathing and are very active, making the meat flavorful and slightly tough.
Skirt steak is a long, thin cut that is especially good for grilling or pan-frying. It has a coarse grain and intense beefy flavor. When sliced across the grain, skirt steak becomes tender and allows for easier chewing. It is also reasonably priced compared to other steak cuts.
Where is Skirt Steak Located on a Cow?
Skirt steak is located on the bottom part of the abdomen along the belly of a cow. It hangs between the front and hind legs when the cow is standing. This cut comes from the beef plate primal or lower portion of the rib primal. When fabricated, the diaphragm muscles are separated from the bone and other connective tissue to produce the skirt steak.
There are two types of skirt steak – the inside skirt and outside skirt. Inside skirt steak comes from the diaphragm muscle on the interior of the ribcage while outside skirt steak comes from the diaphragm muscle on the exterior of the ribcage. Outside skirt is more popular due to its more uniform shape and size compared to inside skirt.
Why Use Skirt Steak for Fajitas?
There are a few reasons why skirt steak is considered one of the best cuts to use for fajitas:
– Flavor – The abundant marbling in skirt steak produces lots of beefy flavor when grilled over high heat.
– Tenderness – When sliced against the grain, skirt steak becomes tender and easy to chew.
– Affordability – Skirt steak is relatively inexpensive compared to other steaks.
– Appearance – The skirt steak’s loose grain appearance resembles the texture of inside round after grilling. This shredded, stringy texture works well visually for fajitas.
Overall, the cut, texture and price makes skirt steak an optimal choice for cooking flavorful and tender beef fajitas.
What is Chicken Breast?
Chicken breast refers to the pectoralis major muscles found on either side of a chicken’s breastbone. This is the largest part of the chicken and makes up about one quarter of the bird’s full body weight.
Chicken breasts are a lean source of protein with minimal intramuscular fat. They are mildly flavored compared to chicken thighs or legs. When cooked correctly, chicken breasts can be juicy and tender. The mild flavor allows them to pair well with the seasonings and toppings used in fajitas.
Where are Chicken Breasts Located on a Chicken?
Chicken breasts are located on the upper front part of the chicken. There are two halves – the right and left pectoralis major muscles. These muscles allow the wings to lift and lower during flight.
When the chicken flaps its wings, the contraction of these large pectoral muscles enables the upstroke motion. When the wings return to the resting position, the pectoralis minor muscle controls the downstroke.
On either side of the breastbone is one breast half. Skin covers the top portion while rib bones and cartilage form the bottom outline of the breast. The tapered end of the breast that is closer to the chicken’s head is sometimes called the tenderloin and is especially lean and tender.
Why Use Chicken Breast for Fajitas?
There are several advantages to using chicken breast for fajitas:
– Lean and low fat – With minimal intramuscular fat, chicken breast fits in with the lighter style of fajitas.
– Mild flavor – Chicken breast has a subtle flavor that pairs well with bold fajita seasonings.
– Meaty texture – When sliced or diced, chicken breast provides a substantial meaty element.
– Cost effective – Chicken breast is typically an affordable cut compared to other meats.
– Cooks quickly – Chicken breasts can cook fast on the grill or skillet to match fajita cooking times.
The combination of quick cooking, mild flavor, lean protein and cost makes chicken breast a smart choice for chicken fajitas.
What are Shrimp?
Shrimp are a type of small, freshwater or saltwater crustacean with 10 legs, slender bodies and long antennae. They are closely related to prawns but generally smaller in size. The meat inside their muscular tails is the edible part of the shrimp.
Shrimp provide vitamin B-12, selenium and astaxanthin which have antioxidant properties. They are also a good source of protein and omega-3 fatty acids. Shrimp are low in fat and calories, making them a healthy addition to fajitas.
Popular shrimp varieties like white shrimp and pink shrimp have sweet, mild, briny flavor. Their texture becomes firm yet tender when cooked just right. These attributes make shrimp an ideal ingredient for sizzling shrimp fajitas.
Where are Shrimp Located in the Ocean?
Unlike cows or chickens, it’s a bit harder to pinpoint exactly where shrimp are located in the ocean. However, here’s a quick overview of their habitat:
– Shrimp live in the shallow waters of the continental shelves around the world’s oceans.
– They prefer soft muddy or sandy bottoms where they can burrow during the day.
– At night, shrimp come out to feed on plankton and aquatic invertebrates near the ocean floor.
– Shrimp migrate vertically in the water column to find food and avoid predators.
– Commercial shrimping occurs in coastal waters where shrimp congregate. The Northern Gulf of Mexico and Southern Atlantic region are prime shrimping grounds.
– Farmed shrimp are raised in man-made coastal ponds filled with brackish water which simulates the ocean environment.
So while shrimp don’t come from an exact cut on an animal, they do inhabit specific coastal regions and depths preferred by each species. Understanding their habitat allows fishermen to harvest wild shrimp and farmers to cultivate farmed shrimp.

Cooking Methods
Authentic fajita flavor comes from quick cooking over high heat. The fastest and most flavorful cooking methods for fajita meat and shrimp include:
Grilling
Grilling skirt steak, chicken or shrimp over direct high heat helps sear in juices while adding delicious charred bits. Meat should be cooked to proper internal temperatures – 145°F for steak, 165°F for chicken. Shrimp cooks very fast, usually 2-3 minutes per side.
Broiling
Broiling mimics grilling by applying intense overhead heat. It works well for fajita ingredients when grilling outside isn’t an option. Cook under the broiler 4-5 inches from heat, flipping halfway through.
Pan Searing
Pan searing in a hot skillet produces caramelization and intensified flavor. Use a small amount of oil and cook meat in a single layer. Flip once during cooking until done.
Griddling
Cooking on a flat griddle or plancha heats ingredients from below. This method works nicely for fajitas with the sizzle factor. Griddling requires less oil and concentrates the sear marks.
All these dry heat methods add smoky, charred flavor while cooking the proteins quickly to match fajita prep time.
Traditional Fajita Flavors
While the meat choices provide hearty flavor, traditional spices, herbs and other ingredients give fajitas their signature Tex-Mex taste.
Common Fajita Seasonings
– Chili powder – This spice blend adds mild heat.
– Cumin – Earthy, aromatic flavor.
– Oregano – Fresh green herb taste.
– Smoked paprika – Adds subtle smokiness.
– Lime juice – Bright, citrusy tang.
– Garlic – Savory, pungent notes.
– Onion – Sweet allium flavor.
– Salt – Essential for bringing out flavors.

Traditional Toppings
– Sautéed peppers and onions – Sweet, smoky flavor
– Salsa – Fresh tomato, onions, lime, cilantro
– Guacamole – Creamy avocado dip
– Sour cream – Cooling contrast
– Shredded cheeses – Melty Monterey Jack, cheddar or queso fresco
