Making a great burger by going to a smaller slider size bun

Burgers are a staple of the summer cooking. Cooking burgers that are from the butcher, Costco in frozen patties is the easy way.  But after my family said some of what I cooked wasn't that good decided to look for something better. Shifted to organic beef from Costco in the 21oz packages. The problem is the 21 oz is an awkward size for dividing up.  There are four us.  Dividing up into 6 was easier and more reasonable amount of 3.5 oz of beef.  But that size is way too small for a hamburger bun, but a slider bun fits.

There are three parts of my sliders that take time - bacon, caramelized onions, and the burgers.  Part of why I think people like my burgers is I am not in a hurry. 

I oven bake the bacon as I find it easier to cook a whole package at once in cookie sheets. Here is a serious cook's recipe for oven baking bacon.  But I don't do it the fast way. I modify the recipe cooking at a lower temperature of 325 for 30-40 minutes until the bacon is starting to brown all over, then turn down the heat to 150 and cook for another 30-45 minutes. I accidentally added the finishing step of 150 for longer time and found I could walk away and not worry about the last finishing.  Everyone likes the bacon and the clean up is much easier not going for a higher temperature. The bacon fat can easily be drained into Tupperware for reuse in recipes that need bacon fat.

Caramelized onions I'll also slowly cook allowing an hour. Here is one recipe with tips. I use butter and olive oil with salt and pepper. Last time I tried a bit of bacon fat.  Slowly cook over medium heat in cast iron. The browning doesn't occur until 30 minutes cooking.  When the caramelized browning covers all the onions, then I reduce the heat and cook for another 30 minutes.

Time for the burgers. Make 3 inch patties.  6 evenly divided from the Costco 21 oz Organic Beef package.  Garlic salt and pepper.  Cook in cast iron skillet or grill 3-4 minutes per side if you like medium rare.  Warm up buns in toaster oven or grill.  Let the burger rest a couple of minutes.  Serve with onions, bacon, and avocado sides.

I'll add pictures to this post if I remember to take some pictures a long the way.
