Gather your ingredients. Preheat your oven to 350 degrees. Mince garlic and measure sauce ingredients into prep bowls.
Prepare the Green Beans
Bring a medium saucepan 3/4 full of water to a boil. Add a teaspoon of kosher salt. Snap the ends off the green beans and put in a bowl. When the water is boiling, slowly add the green beans and cook for 3-5 minutes. Remove from the water with a slotted spoon or spider strainer spoon to a bowl.
Prepare the Bacon
It is your choice, how much bacon you wrap around the bundles of beans. I use our homemade bacon and it is fairly wide so I slice it vertically, then again in half and wrap the bundle. You can use a full strip of bacon for each bundle, a half, or less. The amount of bacon you use may be more or less than stated in the ingredients section.
In a skillet, cook the bacon until it starts to brown on one side slightly. Remove from pan to paper towels to drain and cool. Slice the bacon long-ways or leave whole depending on how you want to wrap your beans.
Make the Sauce
While the bacon is booking, add the sunflower oil, Dijon mustard, brown sugar, balsamic vinegar, and minced garlic to a small bowl and whisk to combine. Season with kosher salt and pepper to taste.
Wrap the Beans
Gather about 5-7 green beans into a bundle and wrap the bacon around the bundle. Place on a sheet pan with the open end of the bacon facing down. Continue until you have no beans left.
Make sure to leave some room around each bundle when placing them on the baking sheet. The bundles need space to "breathe."
Brush sauce on each bundle, covering the top of the bundle nicely. Use as much or as little sauce as you like.
Bake and Enjoy
Place sheet pan with green bean bundles in the oven and bake at 350 degrees for 15 or until the bacon is rendered and crisp.
Serve with meatloaf, chicken, and just about any meat dish, or eat as a snack!
