How to Make Herb Butter Ribeye Steak Sandwich with Caramelized Onions and Havarti Recipe
Step 1: Prepare the Herb Butter
Start by mixing the softened butter with crushed garlic and diced dill in a small bowl. This herb butter will be the secret sauce that elevates your sandwich, spreading a fragrant, creamy layer onto the bread that perfectly complements the richness of the steak and sweetness of the onions.
Step 2: Slice the Ribeye Steak Thinly
For the best texture and quick cooking, freeze the ribeye steak for 10 to 15 minutes beforehand—this firms it up for easy slicing. Then, slice it thinly to ensure every bite delivers a tender, juicy steak experience.
Step 3: Sear the Steak
Heat a tablespoon of oil in a skillet over high heat until shimmering. Add the steak slices, season generously with salt, and cook until they’re golden brown and slightly caramelized. This step locks in the steak’s juices and builds mouthwatering savory flavor. Once done, remove the steak from the skillet and set aside.
Step 4: Caramelize the Onions
Using the same skillet, reduce the heat to medium and toss in the sliced onions. Let them cook slowly for about 15 minutes, stirring occasionally until they become soft, sweet, and golden brown. These caramelized onions add a luscious, slightly sweet layer that perfectly balances the savory steak and creamy cheese.
Step 5: Assemble the Sandwich
Take your baguette and generously spread the herb butter on both halves. Layer on the juicy ribeye slices, followed by the golden caramelized onions, and then add slices of Havarti cheese on top. Each element harmonizes to create a bite packed with layers of flavor and texture.
Step 6: Melt the Cheese
Place the assembled sandwich halves on a baking sheet, then broil in the oven for about two minutes until the Havarti cheese melts just beautifully. Keep a close eye to avoid burning—the goal is a warm, gooey cheese layer that pulls together all those delicious components.
Step 7: Serve and Enjoy!
Slice the sandwich into portions and serve immediately so you can savor the combination of herbaceous butter, seared steak, sweet onions, and melted cheese with every bite. This is comfort and indulgence wrapped into one unforgettable sandwich.
How to Serve Herb Butter Ribeye Steak Sandwich with Caramelized Onions and Havarti Recipe
Garnishes
To enhance presentation and flavor, consider topping your sandwich with fresh microgreens or a sprinkle of coarse sea salt. A light drizzle of balsamic glaze can also add a subtle tang that complements the sweetness of the caramelized onions beautifully.
Side Dishes
This hearty sandwich pairs perfectly with crispy sweet potato fries, a fresh green salad with a tangy vinaigrette, or even a creamy coleslaw. Each side adds contrasting textures and flavors to round out your meal.
Creative Ways to Present
Try cutting the sandwich into finger-sized sliders for an impressive host-worthy appetizer. For a rustic look, serve on a wooden board with small bowls of pickles and mustard on the side. The Herb Butter Ribeye Steak Sandwich with Caramelized Onions and Havarti Recipe is versatile and inviting, making presentation part of the fun.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, wrap the sandwich tightly in plastic wrap or foil and store in the refrigerator. The flavors will meld even more but it’s best eaten within two days for a fresh taste and good texture.
Freezing
This sandwich doesn’t freeze well with the bread intact because it can become soggy. Instead, freeze the cooked steak and caramelized onions separately in airtight containers for up to one month. Reheat and assemble fresh to maintain the best quality.
Reheating
For reheating, unwrap the sandwich and place it on a baking sheet. Warm in a preheated oven at 350°F (175°C) for 10 minutes or until heated through and the cheese is melty again. Avoid microwaving to keep the bread’s texture intact.
FAQs
Can I use a different cut of steak for this recipe?
Absolutely! While ribeye is optimal for its marbling and tenderness, you can substitute with flank steak or sirloin. Just be mindful to slice thinly against the grain to keep the meat tender.
Is there a substitute for Havarti cheese?
Yes! Mild provolone, fontina, or even mozzarella can work well as a creamy, melty cheese alternative if you can’t find Havarti.
How long do the caramelized onions take to cook?
Patience is key here. Typically, onions take about 15 minutes on medium heat to reach perfect caramelization, but cooking longer at lower heat can deepen the sweetness further without burning.
Can I make the herb butter in advance?
Definitely! Herb butter can be prepared up to a week ahead and stored in the refrigerator. This makes assembly quick and ensures maximum flavor infusion.
What type of bread is best for this sandwich?
A crusty baguette is ideal for its crunch and ability to hold the sandwich fillings. However, a sturdy ciabatta or sourdough loaf can also work beautifully.

Perfectly seared steak and sweet onions complement the richness of garlic-dill butter, creating a satisfying and flavorful sandwich, quickly broiled to melt the cheese and unify the flavors.
Ingredients
Herb Butter
- ½ cup unsalted butter, softened
- 3 garlic cloves, crushed
- 1 tbsp fresh dill, diced
Steak and Meat
- 1 lb ribeye steak, thinly sliced
- 1 tbsp salt (adjust to taste)
- 1 tbsp oil (for cooking)
Vegetables & Cheese
- 1 large yellow onion, sliced into half rings
- 4 slices Havarti cheese
Bread
- 1 baguette, sliced lengthwise
Instructions
- Prepare the herb butter: In a small bowl, combine the softened unsalted butter with the crushed garlic cloves and diced fresh dill. Mix thoroughly to create a flavorful herb butter, then set aside so the flavors can meld.
- Slice the steak: For easier slicing, place the ribeye steak in the freezer for 10-15 minutes until firm but not frozen solid; then thinly slice the steak against the grain to ensure tenderness.
- Cook the steak: Heat 1 tablespoon of oil in a skillet over high heat until shimmering. Add the thin steak slices, season evenly with salt, and cook quickly until golden brown on the outside but still juicy, about 2-3 minutes. Remove the cooked steak from the skillet and set it aside to rest.
- Caramelize the onions: In the same skillet, reduce heat to medium and add the sliced onions. Cook slowly, stirring occasionally, for about 15 minutes or until they become soft and golden brown, developing sweet caramelized flavors. Remove the skillet from heat.
- Prepare the bread: Spread the prepared herb butter generously on both halves of the sliced baguette, ensuring full coverage for moist and flavorful bread.
- Assemble the sandwich: Layer the cooked steak slices evenly over the buttered baguette base. Top with the caramelized onions, then place the 4 slices of Havarti cheese on top to cover the meat and onions fully.
- Broil the sandwich: Place the assembled baguette halves on a baking sheet and position under a preheated broiler for about 2 minutes, just until the Havarti cheese melts and becomes slightly bubbly, watching carefully to avoid burning.
- Serve: Remove the sandwich from the oven, slice into 4 portions, and serve immediately while warm and melty.
Notes
- Freezing the steak briefly before slicing helps achieve thin, uniform slices that cook quickly and remain tender.
- Keep an eye on the sandwich during broiling to prevent the cheese from burning.
- Use a high-quality baguette for optimal texture and flavor.
- Adjust salt in the seasoning step to personal taste, especially if the cheese is salty.
- Caramelizing onions requires patience but adds essential sweetness to balance the savory steak.
