How to Make Grilled Ribeye Steak Sandwich with Caramelized Onions, Mushrooms, and Roasted Red Pepper Aioli Recipe
Step 1: Caramelize the Onions and Mushrooms
Begin by heating a tablespoon of olive oil and one tablespoon of butter in a large skillet over medium heat. Add the sliced onions, sprinkle with ½ teaspoon kosher salt and ½ teaspoon sugar if using—it helps speed caramelization. Cook slowly, stirring occasionally, until they turn a deep golden brown, roughly 20 minutes. Add the sliced mushrooms and remaining butter, allowing them to soften and develop flavor together with the onions for another 10 minutes. The result is a gorgeous, sweet, and savory topping that melts in your mouth.
Step 2: Prepare the Roasted Red Pepper Aioli
In a blender or food processor, combine the mayonnaise, lemon juice, olive oil, roasted red peppers, garlic cloves, 1 teaspoon kosher salt, and a dash of cayenne pepper. Blend until smooth and creamy. This aioli is creamy, with a smoky sweetness and a little heat, adding a vibrant and exciting dimension to the sandwich that you won’t forget.
Step 3: Grill the Ribeye Steaks
Preheat your grill or grill pan to high heat. Season each ribeye steak generously with kosher salt. Grill the steaks for about 2 to 3 minutes per side for medium-rare, or adjust the time to your preferred doneness. Let them rest for a few minutes to lock in the juices before slicing thinly against the grain for maximum tenderness.
Step 4: Assemble the Sandwich
Slice the ciabatta rolls in half and lightly toast them on the grill or in a pan until golden and slightly crispy. Spread a generous amount of roasted red pepper aioli on both halves. Pile on the sliced ribeye, followed by the caramelized onions and mushrooms. Finish with a handful of fresh baby arugula for a crisp, peppery contrast. Close the sandwich and get ready to savor every bite.
How to Serve Grilled Ribeye Steak Sandwich with Caramelized Onions, Mushrooms, and Roasted Red Pepper Aioli Recipe
Garnishes
Fresh herbs like chopped parsley or thyme can add a lovely freshness that brightens the rich flavors. You might also consider a few pickled jalapeño slices if you want to dial up the spice and add a little tang.
Side Dishes
This sandwich pairs brilliantly with crispy sweet potato fries or a simple mixed green salad dressed lightly with balsamic vinaigrette. The sides should complement without overpowering, allowing the star sandwich to shine.
Creative Ways to Present
For an impressive twist, serve the steak sandwich open-faced on a wooden board, allowing guests to add arugula or aioli as they please. You could also turn it into sliders with smaller ciabatta rolls for a charming party appetizer or game-day treat.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store the steak slices and the caramelized vegetables separately from the bread to maintain freshness. Keep all components in airtight containers in the refrigerator, ideally for up to 2 days.
Freezing
The individual ingredients like the aioli and cooked mushrooms and onions freeze well on their own but avoid freezing the assembled sandwich to preserve texture and flavor. Thaw frozen components overnight in the refrigerator before use.
Reheating
Gently reheat the steak slices and caramelized vegetables in a covered skillet over medium-low heat to avoid drying out. Toast the bread fresh or warm it separately and reassemble for the best eating experience.
FAQs
Can I use a different cut of steak for this recipe?
Absolutely! While ribeye is wonderfully tender and flavorful, thin-cut sirloin or strip steak can also work well. Just be mindful of cooking times since leaner cuts can cook faster and become tough if overdone.
How do I roast red peppers at home for the aioli?
To roast red peppers yourself, place whole red bell peppers under a broiler or on an open flame, turning until the skin blisters and chars. Then, seal them in a bowl covered with plastic wrap for 10 minutes before peeling off the skin. This method enhances their sweetness and smokiness.
Is the caramelizing step necessary?
Yes! Caramelizing the onions and mushrooms develops their natural sugars, creating deep sweetness and complexity. Skipping this step will result in less flavor and a less satisfying sandwich.
Can I make the aioli without a blender?
Definitely. You can finely mince the garlic and roasted red peppers, then whisk them vigorously with the other aioli ingredients until smooth. It just takes a little more elbow grease but works just as well.
What drink pairs well with this sandwich?
A bold red wine like a Cabernet Sauvignon or Malbec complements the hearty ribeye beautifully. For non-alcoholic options, try a sparkling iced tea with a hint of lemon to refresh your palate.
