Tenderloin Steak Kabobs & Tzatziki Sauce

The secret behind a truly memorable kabob lies not in kabob and a truly great one comes down to the knife work. When you are threading beef, mushrooms, and bell peppers onto the same skewer, every piece needs to be cut to the same size — roughly one inch — so they cook at the same rate. That way, the meat achieves a gorgeous, golden-brown sear at the exact moment the vegetables reach a blistered, tender finish.

Threading those uniform cuts tightly onto stainless steel skewers takes a bit of care. Compress the ingredients just enough to prevent them from spinning on the metal, while still leaving enough surface exposed for the intense heat of the grill to kiss every edge. Drop those well-seasoned skewers onto a screaming-hot surface, and the immediate sear locks in the juicy, medium-rare center of the beef tenderloin.

A Cool and Creamy Tzatziki

To provide a refreshing contrast to the rich, savory char of the beef, this dish is paired with a bright, cool tzatziki sauce. The key to a flawless tzatziki is removing the excess water from the cucumbers. Salt the sliced cucumbers and let them rest for a few minutes, then squeeze them firmly in a towel before mixing. This simple step prevents the sauce from turning thin and watery on the platter.

Once squeezed dry, the cucumbers are pulsed in a food processor with fresh dill, garlic, and whole-milk Greek yogurt. A squeeze of fresh lemon juice brings it all together into a bright, creamy sauce that cuts beautifully through the richness of the steak, giving the entire plate a sophisticated, Mediterranean-inspired feel.

Ingredients Method

Ingredients

  

The Skewer Architecture

• 3 4 to 6-ounce beef tenderloin steaks, cut into uniform 1-inch cubes
• 1 large bell pepper any color, seeded and cut into 1-inch uniform pieces
• 1 large red onion peeled and cut into thick 1-inch wedges (keeping layers intact)
• 12 baby portobello mushrooms stems removed
• 1 teaspoon kosher salt
• 1 teaspoon coarse black pepper
• 2 tablespoons olive oil

The Tzatziki Emulsion

• 1 medium cucumber peeled and thinly sliced
• 1 teaspoon kosher salt for extracting cucumber moisture
• 4 cloves garlic peeled
• ⅓ cup fresh dill roughly chopped
• 2 cups plain whole-milk Greek yogurt
• 1 tablespoon fresh lemon juice from ½ lemon
• ½ teaspoon coarse black pepper
• Warm pita bread for serving

Method

 

Make the Tzatziki

1. Lay the peeled and sliced cucumber onto a double layer of paper towels. Sprinkle evenly with the 1 teaspoon of kosher salt and let rest for 5 to 10 minutes.
2. Wrap the cucumber in the paper towels and aggressively squeeze out the excess moisture. (Drawing out this liquid is critical to prevent a watery sauce).
3. Place the squeezed cucumber slices into the bowl of a food processor along with the peeled garlic cloves and fresh dill. Pulse to combine into a fine mince.
4. Add the Greek yogurt and fresh lemon juice to the processor. Pulse until the sauce is smoothly emulsified. Season with additional salt and the coarse black pepper. Transfer to a serving bowl and refrigerate.

Thread the Skewers

1. Organize the 1-inch beef cubes, bell pepper pieces, red onion wedges, and portobello mushrooms on a clean prep board.
2. Thread the skewers tightly but without crushing the ingredients. Start with 2 pieces of bell pepper, followed by a cube of beef, an onion wedge, and a mushroom.
3. Repeat the sequence, ending with a final chunk of beef to anchor the skewer. (Yields approximately 6 heavily loaded skewers).

The High-Heat Flash Grill

1. Heat a heavy cast-iron grill pan or outdoor grill over maximum heat.
2. Aggressively season the assembled skewers on all sides with the kosher salt and coarse black pepper, then drizzle evenly with the olive oil.
3. Lay the skewers onto the screaming-hot grill. Sear undisturbed for exactly 2 minutes to establish a dark, caramelized crust.
4. Give the skewers a quarter-turn and sear for another 2 minutes. Repeat until all sides are deeply browned, about 6 to 8 minutes total for a flawless medium-rare center.
5. Remove from the heat and allow the meat to rest on a warm platter for 3 minutes before serving immediately alongside the chilled tzatziki sauce and warm pita bread.
