- Garlic Cloves – Imparts a robust flavor; use roasted garlic for a milder taste.
For the Steak Filling
- Steak (Ribeye) – The primary protein, chosen for its tenderness and flavor; alternate cuts include top sirloin or NY strip if preferred.
- Salt – Enhances flavor; adjust to taste based on dietary needs.
- Large Yellow Onion – Sweetens when caramelized, adding depth to the sandwich; can substitute with bell peppers for a different flavor profile.

Step‑by‑Step Instructions for Ultimate Ribeye Steak Sandwich with Herb Butter
Step 1: Prepare Herb Butter
Start by softening 1/2 cup of unsalted butter at room temperature for about 20 minutes until creamy. In a mixing bowl, combine the softened butter with 2 minced garlic cloves and 2 tablespoons of freshly chopped dill. Mix well until all ingredients are fully incorporated, creating a fragrant herb butter. Set this aside to let the flavors meld while you move on to the steak.
Step 2: Slice Steak
Take your ribeye steak, about 1 lb, and chill it in the freezer for 10–15 minutes; this firms the meat and makes it easier to slice. Once firm, remove it and cut into thin strips against the grain. Aim for even pieces roughly 1/4 inch thick for optimal tenderness and quick cooking. Set these strips aside as you prepare to fry.
Step 3: Cook Steak
Heat a large skillet over high heat for about 2 minutes until it’s hot. Add a drizzle of oil, then immediately add the sliced ribeye to the skillet, spreading it out evenly. Season with salt, then cook for about 2–3 minutes until the steak is browned and just cooked through. Once golden, remove the steak from the skillet and set aside, covering it to keep warm.
Step 4: Sauté Onions
In the same skillet, add the sliced large yellow onion and a bit more oil if needed. Reduce the heat to medium-high and sauté the onions for about 5–7 minutes, stirring frequently until they become deeply golden and caramelized. The sweetness of the onions will enhance the flavors of your steak sandwich wonderfully. Once caramelized, remove them from the skillet and set aside.
Step 5: Assemble Sandwich
Take a fresh baguette and slice it lengthwise, being careful not to cut all the way through. Spread a generous layer of the prepared herb butter on both sides of the baguette. Layer with the cooked steak strips and sautéed onions, then top with slices of havarti cheese. This will create a decadent filling that complements the steak sandwich perfectly.
Step 6: Broil
Preheat your oven broiler. Place the assembled sandwich on a baking sheet and broil for about 2 minutes, keeping a close eye to prevent burning. You want the cheese to melt beautifully and become bubbly, while the bread gets a lovely golden crust. This finishing touch adds a delightful texture to your steak sandwich.
Step 7: Serve
Once the cheese is perfectly bubbly and golden, remove the sandwich from the oven. Allow it to cool for a minute before slicing it into manageable portions. Serve your Ultimate Ribeye Steak Sandwich warm, and savor the symphony of flavors and textures that make this dish a true delight at any mealtime!
How to Store and Freeze Steak Sandwich
Fridge: Store the assembled steak sandwich wrapped tightly in foil or plastic wrap for up to 2 days. For best results, keep the meat and bread separate to avoid sogginess.
Freezer: To freeze, wrap each component (steak filling, onions, and baguette) individually in airtight containers or freezer bags. Enjoy the steak filling for up to 3 weeks.
Reheating: When ready to eat, thaw the steak filling in the fridge overnight. Reheat in a skillet over medium heat, adding a splash of water to maintain moisture. Broil the assembled sandwich for about 2 minutes to crisp the bread and melt the cheese once more.
Meal Prep: For easy meal prep with your steak sandwich, prepare and refrigerate the filling for up to 3 days before assembly. Assemble only right before serving for the ideal texture!
Expert Tips for the Best Steak Sandwich
Ingredient Substitutions: Use olive oil instead of butter for a lighter herb topping, or swap havarti with provolone for a different flavor profile.
Steak Tips: Freezing the ribeye for a short time makes it easier to slice thinly against the grain for maximum tenderness in your steak sandwich.
Caramelizing Onions: Cook onions slowly over medium-high heat to achieve deep sweetness; rushing this step may lead to uneven cooking.
Avoid Sogginess: Assemble sandwiches just before serving to keep the bread crispy—store sandwich components separately in the fridge until you’re ready to eat.
Serving Suggestions: Pair your steak sandwich with crispy French fries, a fresh side salad, or crunchy potato chips for a complete meal experience.
Make Ahead Options
These Ultimate Ribeye Steak Sandwiches are ideal for meal prep enthusiasts looking to save time during busy evenings! You can prepare the steak filling by cooking the ribeye and sautéing the onions up to 3 days in advance; just refrigerate them separately to prevent the bread from becoming soggy. Additionally, you can make the herb butter up to 24 hours ahead and store it in the refrigerator. When you’re ready to serve, simply reheat the steak and onions in a skillet, assemble the sandwich with the herb butter and cheese, and broil for a couple of minutes. This way, your steak sandwich will be just as delicious, giving you that gourmet experience without the last-minute rush.
