Step‑by‑Step Instructions for Herb Butter Steak Sandwich with Caramelized Onions and Melted Havarti
Step 1: Prepare the Herb Butter
Begin by mixing ½ cup of softened unsalted butter with 2 cloves of minced garlic and 2 tablespoons of chopped fresh dill in a bowl. Use a fork to blend them together until creamy and well incorporated. This flavorful herb butter will add a rich, aromatic punch to your Herb Butter Steak Sandwich. Set the mixture aside to allow the flavors to meld while you prepare the other ingredients.
Step 2: Slice the Steak
To make slicing easier, place your steak in the freezer for 15-20 minutes until firm but not frozen solid. Once slightly firm, remove it from the freezer and slice the steak thinly against the grain, aiming for ¼-inch strips. This step ensures that your steak will be tender and easy to bite into when you assemble your sandwich.
Step 3: Cook the Steak
Heat 1 tablespoon of oil in a large skillet over medium-high heat until it's shimmering. Add the seasoned steak strips in a single layer, making sure not to overcrowd the pan. Cook for 2–3 minutes on each side, or until they are beautifully golden brown and slightly charred. Once cooked, remove the steak from the skillet and set aside to rest.
Step 4: Caramelize the Onions
In the same skillet, add 1 large sliced yellow onion and reduce the heat to medium. Sauté the onions for about 10 minutes, stirring frequently, until they are soft and golden brown. If they begin to stick to the pan, add a splash of water or a little more oil to prevent burning. Once caramelized, remove the onions from the skillet and set aside.
Step 5: Assemble the Sandwich
Cut a fresh baguette in half lengthwise, then spread a generous layer of the prepared herb butter on both halves. Next, layer on the cooked steak strips evenly, followed by the sweet caramelized onions and a thick slice of melted Havarti cheese. This combination will create a flavor-packed filling for your Herb Butter Steak Sandwich that's delightfully satisfying.
Step 6: Broil the Sandwich
Preheat your broiler on high. Place the assembled sandwich halves on a baking sheet and put them under the broiler for about 2 minutes, keeping a close eye to ensure the cheese melts and bubbles without burning. The heat will create a gooey, mouthwatering layer of melted Havarti atop your savory steak and onions.
Step 7: Serve
Once the cheese is melted to your liking, remove the sandwich from the oven and let it cool slightly before slicing it into portions. Serve your Herb Butter Steak Sandwich with a sprinkle of fresh parsley or dill for garnish, if desired. The combination of rich flavors and comforting textures will make it a standout meal, perfect for any occasion.
How to Store and Freeze Herb Butter Steak Sandwich
Fridge: Store leftover sandwich components separately in airtight containers for up to 3 days. Reheat steak and onions before assembling to retain freshness.

Herb Butter Steak Sandwich with Caramelized Onions and Melted Havarti Recipe FAQs
How do I select the best steak for this sandwich?
Absolutely! When choosing your steak, look for cuts like sirloin, ribeye, or skirt steak for the perfect combination of flavor and tenderness. Opt for fresh meat that is bright in color and free from excess liquid. If you're unsure, ask your butcher for recommendations based on your cooking method.
What is the best way to store leftover Herb Butter Steak Sandwich components?
To keep your leftovers fresh, store components separately in airtight containers in the fridge for up to 3 days. The steak and caramelized onions can be reheated together in a pan over medium heat for a quick refresh before assembling your sandwich.
Can I freeze the steak and onions for later use?
Yes, you can! Wrap the cooked steak and onions tightly in plastic wrap, then in aluminum foil to prevent freezer burn. They can be frozen for up to 2 months. When you’re ready to enjoy, thaw them overnight in the fridge before reheating.
What if my caramelized onions burn while cooking?
If your onions start to burn, quickly add a splash of water or a little more oil to the skillet. This not only deglazes the pan but also helps to lift the burnt bits off the bottom. Keep your heat on medium-low and stir frequently to ensure a nice, even caramelization without burning.
How can I adapt this sandwich for dietary restrictions, like dairy allergies?
Very! For a dairy-free version, substitute Havarti cheese with a dairy-free cheese option, and use vegan butter in your herb butter mix. Ensure your baguette or ciabatta is also dairy-free, and you’re all set for a delicious alternative that everyone can enjoy!
How long can I keep herb butter in the fridge or freezer?
I recommend storing your herb butter in an airtight container in the fridge for up to a week. For longer storage, freeze it in small portions—ice cube trays work great—allowing you to enjoy that tasty flavor whenever you need it. Just thaw as needed!
