Now, for one of my family favorite recipes, Roasted Green Beans with Creamy Gruyere Sauce and Bacon AKA Thanksgiving side-dish domination. Because really, we can only eat so much turkey, so to me, Thanksgiving is all about the sides. This side. This side with crisp tender green beans roasted to perfection with a little salt and pepper then smothered in a creamy Gruyere Sauce that’s bursting with flavor all topped with crispy bacon. Hello Thanksgiving.
These Roasted Green Beans with Creamy Gruyere Sauce were born out of necessity. You see, I was in charge of making the “green bean casserole” for Thanksgiving a few times as a young adult – and I made my grandma’s green bean casserole recipe that has been passed down for generations. And while they were comforting, there is a reason they are only served as an obligatory Thanksgiving side and not throughout the year.
So years passed and I knew I wanted to reinvent the Green Bean Casserole. The green beans still had to be creamy like Grandma’s (in this case creamy AND cheesy) and there still needed to be a crispy element like Grandma’s fried onions – just a little more sophisticated and palate pleasing. Enter Roasted Green Beans with Creamy Gruyere Sauce and Bacon. Enter the new green beans in town. And I’ve been making them to satisfy Thanksgiving requests every year since.
The green beans themselves are infused with flavor by first tossing them with olive oil, salt and pepper then roasting until desired crisp tenderness, about 12-15 minutes. I love roasting green beans because it is the absolute easiest way to prepare them and transforms ordinary green beans into an elegant side dish in minutes.
While our green beans are roasting, we make our easy yet utterly divine Creamy Gruyere Sauce in 5 MINUTES! I really need a separate recipe post just for this elegant cheese sauce because it is AH-mazing on all sorts of veggies, and might just become your new favorite cheese sauce in the world. There’s only one way to find out…
To make this Creamy Gruyere Sauce, melt some butter in a medium saucepan then sauté a shallot followed by garlic then stir in heavy cream. Next, add layers and layers of subtle flavor with a splash of Dijon mustard, and a pinch of McCormick® Dried Thyme, McCormick® Paprika, McCormick® Salt and McCormick® Pepper. Increase heat to medium high and cook until sauce starts to thicken, about 2 minutes. Remove from heat, and stir in mega creamy, sweet, slightly salty, nutty Gruyere cheese until melted followed by lemon juice.
Next, we smother our Roasted Green Beans with our Creamy Gruyere Sauce, add a generous Thanksgiving style amount of bacon and that’s it for one of the quickest, easiest side dishes of your Thanksgiving feast. I won’t tell a soul. Just sit back and prepare to be complimented by all partakers at your Thanksgiving.

This sounds delish! I’m going to leave the bacon off though. It’ll just be green bean yummyness.

Cheryl B. says
We had all the ingredients on hand! DH makes our bacon so it is especially lean and yummy. He was happy to try a new green bean recipe! Thanks from the opposite end of the state!
Jen says
You are so welcome Cheryl! I’m so happy you made these already and loved them!
Jennifer says
Can this be reheated well? I have to bring a side to my mom’s house and I’d love to make this, but I’ll have to make it at home and reheat at her house. Thoughts? This sounds absolutely amazing!!!
Jen says
Hi Jennifer, yes this should reheat great! I would just take care to not overcook your green beans initially. The sauce will thicken once refrigerated so you might want to add a splash of cream on top before you transport it and then it will help creamify the sauce once reheated. Enjoy and Happy Thanksgiving!
