1. Prepare the Beer-Braised Cabbage and Onions:

1. Heat butter and olive oil in a large skillet over medium heat.
2. Add the onion and sauté for 2-3 minutes until softened.
3. Add the chopped garlic and cook for an additional 30 seconds, until fragrant.
4. Stir in the sliced cabbage and cook for an additional 3-4 minutes, until slightly wilted.
5. Sprinkle in the caraway seeds, salt, and pepper.
6. Pour in the beer, reduce heat to low, and simmer uncovered for 10-12 minutes, stirring occasionally, until the liquid has mostly evaporated and the cabbage and onions are tender.
7. Taste and add more salt and pepper if needed. Set aside.

2. Make the Horseradish Mustard Aioli:

1. In a small bowl, whisk together mayonnaise, Dijon mustard, horseradish, lemon juice, honey, and ketchup (if using).
2. Taste and adjust seasoning with salt and pepper. Refrigerate until ready to assemble.

3. Heat the Corned Beef, Cabbage, and Melt the Cheese:

1. Preheat your oven to 350°F (175°C).
2. Line a baking sheet with parchment paper or foil.
3. Layer the corned beef on the sheet pan in 12 small piles (one for each slider).
4. Add a scoop of the beer-braised cabbage and onions on top of each corned beef pile.
5. Place a slice of Swiss cheese over each pile.
6. Bake in the preheated oven for 10-12 minutes, or until the cheese is melted and the corned beef is heated through.

4. Toast the Slider Buns:

1. Slice the Hawaiian rolls in half.
2. Brush the cut sides of each roll generously with melted butter.
3. Place them cut-side up on a separate baking sheet and toast in the oven for 5-7 minutes, or until golden brown.

5. Assemble the Sliders:

1. Spread a generous layer of horseradish mustard aioli on the bottom and top halves of the toasted rolls.
2. Carefully transfer each pile of corned beef, cabbage, and melted cheese onto the bottom halves of the rolls.
3. Add a slice of dill pickle on top, then place the top halves of the rolls to complete the sliders.

6. Serve:

Serve the sliders warm, with any remaining aioli on the side for dipping. Perfect for a St. Patrick’s Day celebration or any time you’re craving a festive, Irish-inspired bite! 🍀
