Perfectly golden crisp sour dough bread is piled high with a tender, flavorful, juicy grilled hamburger patty, topped with caramelized onions, mushrooms, bacon, and three kinds of melted cheese. All to create these Ultimate Patty Melts!

I woke up one night last week thinking about… Patty Melts! (It happens! A lot!) Why was I thinking about Patty Melts in the middle of the night, you ask? Wish I could say it was a hormonal thing and call it good! (Sounds so much saner than the real reason!)
Well…I had a really busy schedule that week, and I was ticking off in my mind what I had on hand to make a menu for dinners that week. There was a pound of hamburger out in the freezer…but I didn’t have any hamburger buns!
I couldn’t stand the thought of having to go to the store! (Real life problems my friends! Walmart shopping is not my favorite!)
Next thought… Patty Melts! (This is what all women do in the wee hours of the morning…think of Patty Melts!) A great cross between a grilled cheese and a hamburger.

There I sat at three o’clock in the morning creating the Ultimate Patty Melt in my head! It would be loaded with bacon, fresh sauteed mushrooms, caramelized onions and lots of ooey-gooey melted cheese! This was going to be EPIC!!!
Any awesome sandwich is only as great as its ingredients! So…
Ingredients List
- 1 pound ground beef
- 1 pound bacon, cooked
- 2 cups sliced fresh mushrooms
- 1 medium-sized onion
- 8 slices Munster cheese
- 8 slices Colby jack cheese
- 8 slices sour dough bread, or rye bread
- Butter for bread
How to Make the Ultimate Patty Melt…
Divide the hamburger into four equal portions. Form 4 patties, 1/4 of an inch thick, into the shape of your bread. For me, that was a rectangle.
TIP: You want to make sure that your hamburger patty covers the bread.
Season with salt and pepper to taste. Grill on the BBQ, or in a Grill Pan on your stovetop.

Cook 3–5 minutes or until patty is golden brown. Flip burgers over and grill the other side.

Topping Prep
Meanwhile…in other words…as the burgers are cooking, in a medium skillet over medium heat, add 1 tablespoon butter. Melt butter and add mushrooms and thinly sliced onions.

Cook until mushrooms are tender and onions are slightly caramelized or tender, whichever you prefer!
Back to your burgers… Remove patties from pan and set aside.

Let’s talk bread! What type of bread is used in a patty melt?
The original Patty Melt was made on rye bread. The birds at this nest don’t love rye bread. So I used a beautiful sour dough.
TIP: You can use whatever type of bread is your favorite! Like I always say…get creative in the kitchen! Have FUN!
How To Grill the Ultimate Patty Melt
Butter one side of each slice of bread. Place the slices of bread, buttered side down, on a hot griddle.
Cover one half of the bread slices with Munster cheese, on the other slices, Colby Jack. Now I was out of sliced Colby Jack, so I used grated cheese. You can use sliced. (It’s much easier… trust me!)

Place the grilled hamburger patties on top of the Colby Jack cheese. On the Munster cheese place three slices of pre-cooked bacon.

Once the cheese is melted and all gooey…and the bread is a beautiful golden brown… Add the mushrooms and onions on top of the burgers!
WOW! That patty melt looks mighty tasty! (I may have been drooling at this point…just another reason to wear an apron when cooking! Face it…they’re big girl bibs!)

Now for the tricky part…bringing it all together! It’s time to marry two sides together, bacon and burger, without losing anything during the process! (This requires some MAD flipping skills! Thankfully, any mother who has had more than one small child at a time can do this with her eyes closed!)
TIP: Use a spatula to do this! (Don’t use your bare hands!) Also, I recommend placing the bacon side on top of the burger side and pressing it all down together with the back side of your “flipper”! (That’s the technical term for a flapjack-burger-grilled cheese-flipper thingy!)

Look at that Patty Melt! Isn’t it a thing of beauty! (Yep, this is what men find beautiful ladies!)
What to serve with a Patty Melt if you’re making this for dinner?
I made oven-fried potato wedges with garlic salt and a heavy sprinkle of Parmesan cheese! (Cause at this point calories are not even worth mentioning!) A great compliment to this delicious sandwich. There are lots of great options though…

The great thing about a patty-melt this size…is that it’s an entire meal! Truth be told…me and Mr. Nest could only eat half…they are HUGE! I’ll share a secret with you though…we ate the other halves the next day! I heated them up in my air fryer, and they were as crispy and tasty as the first day!
I suggest adding a little mustard to this sandwich! It really kicks it up! If you’ve never added Munster cheese to your grilled cheese…do it!!! The melt factor is out of this world!!!
Try it sometime…until then…TRY THESE Ultimate Patty Melts!

Wow, I made your ultimate patty Melts and they were a big hit. I made extra so that there would be leftovers to see how they were reheated and they were even better the next day. I served the leftovers as open faced sandwiches stacked on grilled homemade white bread.
