This recipe for Oven Roasted Green Beans with Bacon and Onion is pretty much a Facepalm Idea, for me.  It’s one of those ideas that is so obvious, it hurts. I feel the need to whack myself in the forehead, à la “V-8”, so badly does it pain me to think of all the wasted years I haven’t been doing this.

Question: Is a purple green bean still a green bean? Look at these beautiful PURPLE “Green” Beans that we got at the Farmer’s Market the other day. Aren’t they gorgeous? And just wait till you see what they look like when we cut them open!

The reason it cuts so deep is that I’ve been roasting vegetables for years. Broccoli, cauliflower, carrots, parsnips, butternut squash…ALMOST, you name it, and I’ve roasted it. Most vegetable flavors really do improve when we roast them. And yet, I’ve been neglecting to roast my green beans.

Why do vegetable flavors improve when you roast them in the oven, you ask? I’m so glad you did! Especially if you’re someone who is challenging yourself to up your cooking game, a bit. This next bit is important, and all good cooks know this secret. So pay attention.

When we cut the purple “green” beans open, they were this gorgeously contrasting bright green color on the inside. I just love how purple and green look right next to each other. It’s that complementary color thing! They’re shiny from having been liberally drizzled with olive oil. 

Why Should You Roast Vegetables?

You should roast vegetables because roasting them causes something to happen that is called the Maillard Reaction. (This is not the reaction you see in the Cranky AFLAC Duck. That’s the Mallard Reaction. Neither is it the raised, impatient eyebrow, you see from Leroy Jethro Gibbs, when his medical examiner, Ducky, on NCIS, goes off on another verbal tangent. Again,  that’s also known as the Mallard reaction. The MAILLARD Reaction is something quite different.)

The Maillard Reaction is when the natural sugars in veggies, having been exposed to sufficient heat, start to turn brown, and caramelize. This releases a brand new bunch of aromatic flavor compounds which were not present before. Yes, it’s chemistry. But fear not, it’s chemistry of the very best kind.
Let’s face it, and we all know this, intuitively: in the words of Chef Anne Burrell, “Brown Food Tastes GOOD!”. (And you say the word “GOOD” with a growl.)

Tips for Improving Simple Roasted Green Beans: 

So really, there’s truly not much to it. But each thing I mention in this section is important, and you shouldn’t skip one of them. Mostly, it involves bacon, and onions.

  1. Take a couple of strips of bacon, and cut each strip into lardons. That means cut them into nuggets about the width of your index finger. Blame the French for the fancy name. Personally, I prefer thick cut bacon. Sprinkle the lardons on the sheet pan to roast with the green beans.
  2. Dice an onion. Sprinkle that on too.
  3. Season assertively with sea salt, and freshly ground black pepper. I like my pepper like I like my men. Coarse. OK, that was a joke, except for the how I like my ground pepper part.
  4. Finally, don’t hesitate to use TWO sheet pans, because that’s how the green beans will develop color faster. The Maillard Reaction. Remember? You’re so smart! If you crowd them all onto one pan, snuggled up together, they’ll STEAM, not brown. And brown food tastes GOOD! Remember? Yes, I know you’ll have to wash one more pan, but it will be worth it. Promise.

Last of all,  our biggest surprise of this recipe was….drumroll please….

When roasted…purple green beans turn a slightly disappointing shade of …green. Oh, well. They still taste great!!!

Oven Roasted Green Beans with Bacon and Onion

Roasting Green Beans is easy! Adding bacon lardons and diced onion makes it even better. What an easy and tasty way to eat your fresh veggies!

Prep Time 10 minutes
Cook Time 20 minutes
Total Time 30 minutes

Ingredients

  • 2 lbs. green beans, ends broken off
  • 2 slices thick cut bacon, cut into lardons
  • 1 medium onion, diced
  • 2 Tablespoons of olive oil
  • sea salt, to taste
  • freshly ground black pepper, to taste

Instructions

  1. Preheat oven to 400º.
  2. Spread green beans out over a couple of sheet pans.
  3. Sprinkle each pan with half the bacon lardons, and half of the diced onion.
  4. Drizzle each pan with a tablespoon or so of olive oil.
  5. Season each pan assertively with salt and pepper. Mix the contents of each pan with your hands to be sure oil and seasoning are evenly distributed.
  6. Roast for about 15 - 20 minutes, or until the bacon looks crispy and the green beans have begun to slightly caramelize. Check on things when they start smelling good.

Notes

If your green beans have strings, you'll want to remove them when you break off the ends.
Lardons are merely little nuggets of bacon, about as wide as your index finger. Blame the French for the fancy name.
If you're using thin cut bacon, use 4 strips, instead of 2.

If you were looking for something a tad different, in how to prepare your green beans, I’ve got two other green bean recipes that I’ve been making for years. One, is quite southern and old fashioned, my Green Beans and Potatoes. The other is one I make nearly every Thanksgiving and Christmas, and it’s a bit more refined. It’s Ina Garten’s Green Beans Gremolata

Now, off to your garden, or your nearest Farmer’s Market with you! And get roasting! Right after you share this recipe, if you please. That would be a great way to thank me!
