- ½ teaspoonblack pepper

- 59⅛ mldry white wine
- 2 tablespoonsfresh parsley(chopped)
- 2 tablespoonsolive oil
Instructions
- 1
Begin caramelizing the onions by heating 2 tablespoons of butter with olive oil in a large skillet over medium heat. Add sliced onions and cook for 20-25 minutes, stirring occasionally, until they turn golden brown and sweet.
Tip: Low and slow is key—resist the urge to increase heat, as this ensures proper caramelization without burning.

While onions cook, prepare the herb butter by mixing 4 tablespoons softened butter with minced garlic, fresh thyme, salt, pepper, and paprika in a small bowl.
Tip: Make herb butter ahead and refrigerate if desired, then soften slightly before serving.

Once onions are caramelized, deglaze the skillet by pouring in white wine and scraping up browned bits. Simmer for 2 minutes until wine reduces slightly, then set aside.
Tip: The wine adds depth and prevents the onions from being one-dimensional in flavor.

Preheat your grill to medium-high heat (around 400°F). Pat lobster tails dry with paper towels and brush the meat side lightly with olive oil.
Tip: Dry lobster ensures better grill marks and prevents sticking.

Place lobster tails meat-side down on the grill and cook for 5-7 minutes until the meat becomes opaque and develops char marks. Flip and cook shell-side down for another 3-4 minutes.
Tip: Lobster cooks quickly—watch carefully to avoid overcooking, which makes the meat tough.

During the last minute of grilling, place a lemon half cut-side down on the grill to char and release juices.
Tip: Grilled lemon adds brightness and a smoky citrus note to the dish.

Transfer grilled lobster tails to a serving platter. Top each tail generously with herb butter, then spoon caramelized onions over the top.
Tip: The warm lobster will melt the herb butter perfectly—don't skip this step.

Garnish with fresh chopped parsley and serve immediately with grilled lemon wedges on the side.
Tip: Serve with crusty bread to soak up the delicious pan juices and butter sauce.
