Step 1

Bring a large pot of salted water to a boil. Add green beans and cook until tender, about 3-4 minutes. Drain under cold running water for a minute and set aside.

Step 2

Add bacon to a large skillet and cook over medium-high heat until browned on both sides and crisp, about 3-4 minutes. Leave the bacon fat in the skillet and transfer the bacon onto a plate.

Step 3

In the same pan, add onion and garlic and sauté until fragrant, about 1 minute.

Step 4

Stir in the blanched green beans and cook until warmed through, about 1-2 minutes. Stir well to coat.

Step 5

Return the bacon to the skillet and add balsamic vinegar, salt, and pepper. Toss to combine and cook for one more minute. Serve immediately.
