1/2cupyellow onion, finely chopped,1/2 medium onion
4slabsthick cut bacon, chopped to 1/2" pieces6 to 7 ounces
1 1/2tbspbutter
2tspsalt, for blanching water
Instructions
Prepare an ice bath in a large bowl. Bring a large pot of water to a boil, (4 or 5 quarts), add 2 tsp salt and place the beans in to blanch. Boil for 4 minutes. Strain the water and place the beans in the ice bath, or use a kitchen spider to transfer the beans to the ice water. Let cool for 2 minutes, then remove them from the water and place on paper towels to dry.
Heat a tall sided skillet on medium heat and cook the bacon pieces until nicely browned and the fat has rendered, 8 minutes. Remove the bacon from the skillet and place on paper towels to drain.
Spoon out all but 2 tablespoons of the bacon grease, add the butter and saute the onions on medium heat, 4 minutes. Next, put the beans in the skillet and toss to combine. Scrape up any brown bits from the pan by adding 1 tablespoon water and scraping the pan with a wooden spoon. Cook, stirring occasionally for 6 minutes.
Add the bacon to the skillet and fold in. Allow to warm, 1 or 2 minutes. Place the beans in a serving dish and serve hot.
Notes
The beans can be reheated in a microwave but the beans tend to get overdone and kind of wilt and don't look as nice.
The beans can be blanched up to 6 hours in advance. Dry them well and place in a plastic bag and refrigerate.
If you use a non-stick skillet, you probably won't get the fond in the skillet so you can skip adding the tablespoon of water.
