My favourite Mexican recipe has to be Marinated Beef with Fresh Guacamole. The bold, smoky flavours of Carne Asada Fiesta, as I like to call it, come from well-seasoned, tender beef, perfectly grilled and sliced, then paired with the creamy richness of guacamole. This combination is a staple of Mexican street food and home cooking alike, offering a satisfying mix of textures and flavours.

The Magic of a Good Marinade

At the heart of Marinated Beef with Fresh Guacamole is the marinade. Traditional Mexican marinades often feature citrus juices like lime and orange, which not only infuse the beef with tangy brightness but also help tenderise it. A blend of spices—often including cumin, chilli powder, and smoky paprika—creates a deep, layered flavour. Garlic and fresh coriander add an extra punch, making every bite of the beef vibrant and mouth-watering.

Once marinated, the beef is typically grilled over an open flame, giving it a lightly charred, smoky crust while keeping the inside juicy and flavourful. This technique is key to achieving that signature carne asada taste—bold, slightly charred on the edges, yet tender and bursting with flavour.

Guacamole: The Perfect Partner

No Marinated Beef with Fresh Guacamole is complete without a generous helping of obviously homemade guacamole. Creamy, fresh, and slightly tangy, guacamole balances the richness of the grilled beef beautifully. At its core, it’s a simple preparation—ripe avocados mashed and mixed with lime juice, salt, and often diced tomatoes, onions, and coriander. The result is a smooth, flavour-packed dip that complements the beef perfectly.

Serving It Up

There are endless ways to enjoy Marinated Beef with Fresh Guacamole. Wrapped in warm corn tortillas with a spoonful of guacamole, it makes for a satisfying taco. Served alongside rice and beans, it becomes a hearty and comforting meal. Even on its own, with a squeeze of lime and a fresh salsa, this dish is a celebration of bold Mexican flavours.

For anyone who loves smoky, marinated meats and creamy, flavourful guacamole, Marinated Beef with Fresh Guacamole is a must-try. It brings the warmth and vibrancy of Mexican cuisine to the table, making every bite a delicious experience.

Notes

Here are some tips to ensure your Marinated Beef with Fresh Guacamole turns out superb every time:

For the Carne Asada/Marinated Beef:

Marinate for Maximum Flavour – At least 2 hours is essential, but overnight marination will make the beef even more flavourful and tender. The citrus juices help break down the meat fibres.
Room Temperature Before Cooking – Take the marinated steak out of the fridge 30 minutes before cooking. This ensures even cooking and better caramelisation.
High Heat for a Perfect Sear – Whether grilling or pan-searing, make sure your cooking surface is very hot before adding the steak. This creates a delicious char on the outside while keeping the inside juicy.
Don’t Overcook – Flank and skirt steak are best cooked to medium-rare or medium (about 4-6 minutes per side). Overcooking can make them tough.
Rest Before Slicing – Let the steak rest for 5 minutes before cutting. This allows the juices to redistribute, keeping it tender and moist.
Slice Against the Grain – Cutting against the grain (perpendicular to the muscle fibres) ensures each bite is tender and easy to chew.

For the Guacamole:

Use Ripe Avocados – They should yield slightly when pressed but not be mushy. Overripe avocados can taste bitter, while underripe ones are too firm and bland.
Mash to Your Liking – If you like a chunkier guacamole, mash it lightly with a fork. For a smoother texture, use a spoon and mix well.
Balance the Flavours – Lime juice adds freshness, onions add a little bite, and tomatoes add sweetness. Adjust the salt and lime juice to taste.
Keep It Fresh – Guacamole can brown quickly. To keep it green, store it with a layer of plastic wrap pressed directly onto the surface to prevent oxidation.

Bonus Tips:

For an extra smoky flavour, grill the steak over charcoal or use smoked paprika in the marinade.
For a spicy kick, add finely chopped jalapeños to the guacamole or a pinch of cayenne to the marinade.
For ultimate tacos, warm the tortillas on the grill or in a dry pan for a few seconds to make them soft and pliable.

Follow these tips, and your Marinated Beef with Fresh Guacamole will be an absolute showstopper!
