Wash, trim, and drain the green beans (1 pound). Lay the beans out in a single layer on clean dish towels then roll it up. Allow the beans to dry while you cook the onions.
In a large, high-sided skillet, cook the bacon over medium heat, until it begins to release about 1 tablespoon or more of fat.
Add the onion (1/2 cup) to the skillet with bacon (1/2 pound) and cook until the bacon is crisp. Stir in the garlic and cook until fragrant, about 1 minute. Transfer bacon and onion to a small bowl, leaving bacon fat in the skillet.
Discard all but 1 tablespoon of fat, leaving in the skillet. Turn the heat up to medium-high and add dried beans. Sauté, using tongs to flip the beans, and season with salt (1/4 teaspoon) and pepper (1/4 teaspoon), until tender about 5-7 minutes.
Add the bacon and onion back to the skillet. Serve.
Notes
Dry the beans. After washing, dry them really well with a clean kitchen towel (or paper towels). Dry beans sauté — wet beans steam.
Start with snappy beans. Fresh green beans should feel firm and “snap” when you bend them. Skip beans with soft spots, blemishes, or discoloration.
Cook to your preferred tenderness. I like mine al dente with a little bite, but you can sauté a minute or two longer for softer beans.
Turkey bacon works (with one tweak). If you swap in turkey bacon, add a tablespoon of butter or oil to sauté the onions since turkey bacon doesn’t render much fat.
Add almonds for an elegant twist. A sprinkle of sliced or slivered almonds (plus an optional squeeze of lemon) leans into a Green Beans Almondine vibe — so good with steak or roast chicken.
Want to skip the bacon? I get it — add a handful of freshly grated Parmesan at the end for salty, savory depth.
