How to Make this

FAQ
Ultimate Green Bean Casserole Recipe Substitutions and Variations
- Bacon: Try turkey bacon or even a vegetarian bacon alternative for a lighter twist
- Cream of Mushroom Soup: You can whip up a homemade version by stirring together butter, flour, sautéed mushrooms and milk or even use cream of celery soup instead
- Cheddar Cheese: If you want a different flavor, Monterey Jack or even a bit of smoked provolone works nicely
- Mushrooms: In a pinch, shiitake or portobello mushrooms can give you a more intense flavor than the standard white button mushrooms
- Crispy French Fried Onions: For that crunch, try using toasted panko breadcrumbs or even shredded crispy tortilla chips if you’re feeling adventurous
Pro Tips
1. Try salting the water way before you cook the green beans so they get seasoned right from the start, it makes a big difference in the final flavor.
2. Be extra careful not to overcook the bacon. Crisp is good, but if it gets too dark, it might lend a burnt taste that can take away from the sauce.
3. When stir-frying the mushrooms, let them sit undisturbed for a minute or two. This helps them get nice and brown which adds a richer flavor.
4. Always do a quick taste check of the sauce before tossing everything into the dish. A little extra salt or pepper can really bring out all the flavors in your casserole.
