I tried recipes from Alton Brown, Ree Drummond, and Alex Guarnaschelli to find the best green-bean casserole. One fits better at a barbecue than Thanksgiving dinner.

• I made Alex Guarnaschelli, Alton Brown, and Ree Drummond’s green-bean casseroles. 
• Guarnaschelli’s casserole tasted like something from a high-end steak house.
• Drummond’s version was the least traditional, and Brown’s was the closest to my go-to recipe. 

Green-bean casserole is a nonnegotiable Thanksgiving side for me.

My go-to is the standard recipe made with canned green beans, condensed cream-of-mushroom soup, and French’s fried onions.

But to make sure I’m not missing out on something better, I followed recipes from three celebrity chefs: Alton Brown, Ree Drummond, and Alex Guarnaschelli.

Here’s how they stacked up in my attempt to find the best green-bean casserole.
