Ingredients
- Three rib-eye steaks weighing 8 ounces each
- Butter, as needed (Optional), about 3 tablespoons
- Pinch of salt and ground black pepper to taste
- One tablespoon of butter (Optional)
- Tablespoon of garlic-infused oil
- Teaspoon of brown sugar
- Large onion, thinly sliced after being halved
- Tablespoon of red wine vinegar
- Five tablespoons of prepared pesto sauce
- Two tablespoons of mayonnaise
- Two teaspoons of freshly squeezed lime juice
- Quarter cup of melted butter (Optional)
- Quarter teaspoon of onion powder
- Quarter teaspoon of garlic powder
- Pinch of salt
- Loaf of ciabatta bread, horizontally split in half
- Four slices of Muenster cheese
Step 1
Begin by gently coating each steak with a luscious tablespoon of butter, ensuring an even spread, then generously season with a pinch of salt and pepper to enhance the flavors. Next, delicately place the seasoned steaks in separate vacuum-seal bags, readying them for a transformative cooking process.
Step 2
Seal the bags securely, immersing them in a soothing water bath alongside a trusty sous vide cooker set precisely at 130 degrees F (54 degrees C). Allow the steaks to cook slowly and tenderly until they reach the perfect balance of firmness on the outside and a juicy, reddish-pink center, typically achieved after an hour of patient cooking.
Step 3
In a spacious nonstick skillet, combine another tablespoon of butter with aromatic garlic oil and a touch of brown sugar, allowing the ingredients to meld together over a gentle flame. As the butter melts and the mixture becomes fragrant, introduce a layer of sliced onions to the pan, cooking them until they turn translucent and sweet, a process that takes approximately 5 minutes. Splash in a hint of vinegar, cover the skillet, and reduce the heat to a gentle simmer. Stir occasionally, adding a drizzle of water if necessary, until the onions caramelize into a glorious golden hue, which usually takes around 20 minutes.
Step 4
For a burst of fresh flavors, whip up a zesty mixture of pesto sauce, creamy mayonnaise, and a squeeze of lime juice in a bowl. Stir the ingredients until they harmonize beautifully, then cover the bowl with a snug layer of plastic wrap and let the flavors meld in the refrigerator until they are ready to grace the dish.
Step 5
As the anticipation builds, preheat the oven to a toasty 325 degrees F (165 degrees C) to prepare the bread for its starring role. In a separate bowl, combine melted butter with hints of onion powder, garlic powder, and a sprinkle of salt, creating a savory concoction that will elevate the bread slices to new heights. Gently brush this flavorful mix over both sides of the bread, then carefully place them on a baking sheet, adorning one piece with a generous layer of Muenster cheese.
Step 6
Slide the baking sheet into the preheated oven, allowing the bread to transform into a crispy, golden delight over the course of approximately 15 minutes.
Step 7
Meanwhile, heat up a grill pan over medium-high heat, eagerly awaiting the moment to unveil the succulent steaks. Retrieve one steak from its cozy bag and sear it on the grill pan until a tantalizing brown crust forms on each side, typically taking around a minute per side. Repeat this mouthwatering process with the remaining steaks, ensuring each one is cooked to perfection before letting them rest for a brief 5 minutes. Finally, slice the steaks thinly against the grain to maximize tenderness and flavor.
Step 8
To assemble the masterpiece, generously spread the prepared pesto mixture over the now golden-brown bread, then layer on the sizzling steak slices and the caramelized onions. With precision and care, slice the sandwich into six delectable portions, ready to be savored and enjoyed with every bite.
Extra Tips & Suggestions
- 1. Keep your succulent rib-eye steak fresh by storing it in an airtight container in the refrigerator. This will help maintain its juicy flavor and prevent it from drying out.
- 2. If you have leftover ciabatta bread, wrap it in a clean kitchen towel and store it at room temperature. This will help preserve its crusty exterior while keeping the inside soft and fresh.
