Grass-Fed Steaks with Kalamata-Olive Chimichurri

These pan-seared sirloin steaks offer a sophisticated twist on a classic Argentinian favourite. By swapping some traditional herbs for salty Kalamata olives and sweet shallots, the chimichurri provides a punchy, Mediterranean-inspired finish that perfectly complements the rich, earthy depth of grass-fed beef. The rub of paprika and garlic ensures a beautifully spiced crust, making every bite succulent and full of character.

As a diabetes-friendly main course, this dish focuses on lean protein and heart-healthy fats from the olive oil and olives. It is a satisfying, low-carbohydrate option that feels indulgent without being heavy. Serve the sliced steak with a side of steamed seasonal greens or a crisp watercress salad for a balanced and nutritious midweek dinner or an impressive weekend meal.

How to make Grass-Fed Steaks with Kalamata-Olive Chimichurri

Heat 2 tablespoons oil in heavy medium skillet over medium heat. Add sliced garlic, red pepper, and bay leaf. Stir until fragrant, about 1 minute. Add shallots and sauté until just translucent, about 2 minutes. Remove from heat; stir in parsley, olives, and vinegar. Add 1 tablespoon water. Add more water by teaspoonfuls to thin as needed. Season chimichurri with salt and pepper. DO AHEAD: Can be made 2 hours ahead. Let stand at room temperature.

Rub steaks with 1 tablespoon oil and pressed garlic. Sprinkle both sides of each steak with 1/2 teaspoons paprika, 1/4 teaspoons coarse salt, cayenne, and generous amount of black pepper. Let stand at room temperature 30 minutes or up to 2 hours.

Preheat oven to 204°C. Brush heavy very large oven-proof skillet (preferably cast-iron) with oil. Heat over high heat until almost smoking. Add steaks. Cook until browned, about 5 minutes. Turn steaks and transfer skillet to oven. Roast until instant-read thermometer inserted horizontally into steaks registers 43°C to 46°C for rare, about 10 minutes.

Let steaks rest 5 minutes. Thinly slice crosswise. Spoon chimichurri over.
