👨‍🍳 Step-by-Step Instructions
Step 1: Prep the Cheese
Let all sliced cheeses rest at room temperature for ~15 minutes so they melt more evenly.

Step 2: Cook the Bacon
Place strips on a foil-lined baking sheet and bake at 400°F for 15–20 minutes. Transfer to paper towels to crisp.

Step 3: Butter the Bread
Generously butter one side of each bread slice. Set 4 aside for tops, 4 for bottoms.

Step 4: Assemble the Sandwiches
Lay bottom slices (butter side down) on a cool cutting board or in a cold skillet. Layer cheeses, add bacon, drizzle with ranch. Add optional jalapeños or onions. Top with remaining bread slices (butter side up).

Step 5: Grill to Perfection
Heat skillet to medium-low. Cook sandwiches for 3–4 minutes per side until bread is golden and cheese melts. Flip gently and press lightly for full melt.

Step 6: Rest & Serve
Let sandwiches rest 1 minute before slicing. Cut diagonally and serve hot—cue the cheese pull.
