Skirt Steak Fajitas with Avacado Cream

Jump to Recipe

If you are at the market this week and find yourself looking at a nice skirt steak and some perfectly ripe avocados, this is the recipe for you to try; Skirt Steak Fajitas with Avacado Cream. The steak is marinated in a flavourful mix of cilantro and lime, then grilled to perfection, thinly sliced and topped with bright red pepper, onion and creamy avacado. To eat, wrap in a tortilla to create an easy, handheld meal that everyone enjoys.

I like a skirt steak for these fajitas because, it absorbs the flavourful marinade perfectly and, when cooked medium rare and sliced across the grain, it is a moist and very tasty cut of meat. The outside will have a nice, brown crisp grill flavour and the inside should be a nice pink medium rare. Medium Rare is cooked to 135F. If you can’t find a skirt steak to make this, try any other marinating steak and you will be happy, but the skirt steak cut is definitely my favourite.

Instead of making a regular Guacamole, which you can always try if you like, I paired the Fajitas with an Avacado Cream Sauce. It is a bit lighter tasting and makes your Avocados go a further. 🥑 Bonus, it is also lovely as a dip with tortilla chips and salsa🥑.

My favourite vegetables to try on the Skirt Steak Fajitas are Red Peppers, Onions and Mushrooms, which are featured here. You can also top with any colour peppers, tomatoes, lettuce, cheese, salsa, hot sauce of choice🌶️, or just about any other toppings which you prefer and have handy in the Galley.

Grill any combination of vegetables you like for toppings
