Why you’ll love it

Thanksgiving can be stressful, so I wanted to infuse as much flavor into a traditional green bean casserole as possible while keeping it ultra low effort. The best way to do that? Fresh, irresistible, high-quality ingredients! Everyone will definitely notice the difference it makes.

Making green bean casserole with condensed soup is a tried-and-true method, but you’ll fall in love with using Zoup! Portabella Mushroom Bisque instead. Each jar contains soup that’s kettle-cooked in small batches from a classic French recipe, so your casserole will get a major upgrade.

What you’ll need

  • Green beans – use either fresh or frozen
  • Zoup! Good, Really Good® Portabella Mushroom Bisque – it’s a rich and creamy blend of mushrooms along with aromatic herbs, savory seasonings, and Zoup!’s homestyle veggie broth. It’s made with no artificial ingredients or preservatives.
  • Fried onions – using a premade variety from the seasoning aisle like French’s makes it easy
  • Cheddar cheese – grate your own for the best taste and texture

Pro Tip

Zoup! products are available for purchase at select retailers across the country, through Instacart, and online at ZoupBroth.com, Walmart.com, and Amazon.com.

How to make fresh green bean casserole

This is an overview with step-by-step photos. Full ingredients & instructions are in the recipe card below.

draining green beans in a colander and then adding to a baking dish with mushroom bisque

Preheat the oven. In a large pot, boil the green beans. Rinse them in a colander under cold water to stop them from further cooking. Drain them well, and add to a 9×13 baking dish along with the jar of mushroom bisque.

Add in half of the fried onions. Toss well, and spread into an even layer in the casserole dish. Sprinkle on the cheddar cheese and the rest of the onions. Bake until hot and bubbly!

Helpful tips

  • After boiling the beans, it’s important to rinse them in cool water so that they don’t continue cooking and then overcook in the oven.
  • The beans in this casserole are quite soft by the time baking is finished, so if you prefer more tender-crisp green beans, reduce the boiling time.

Substitutions and variations

  • Adding some bacon bits or chopped cooked bacon would be delicious!
  • You can make this without the cheddar if you prefer. Parmesan cheese would go well, or simply omit the cheese if desired.

Leftovers and storage

  • Leftovers will keep in the fridge for a few days, but keep in mind the fried onions will soften up the longer they sit. For this reason, I don’t recommend freezing leftovers.
  • To reheat, either reheat in the oven at 350F or in the microwave until warmed through.

    1. Hi! I didn’t think it was really soupy. You’re welcome to experiment, though. Cream would make it more liquidy unless you cook it down more.

  1. Hi Natasha! Would it be okay to leave the cheddar cheeese out of the recipe? Or would it compromise taste? Thanks so much!

    1. That’s totally fine – I actually suggest that as an option in the blog post. 😀 Hope you love it and Happy Thanksgiving to you!

            Made this for our TG feast and it was a HIT. I found the ZOUP at my local Sprouts store. Used 2 lbs of trimmed Haricot Verts vs 1 lb of of regular green beans and the consistency was perfect, not soupy or dry. Plus extra sharp cheddar freshly grated and those onions !
