A super tasty version of a classic, made from scratch using fresh ingredients. This green bean casserole is a family favorite that everyone will love!
I love the holidays and all the classic recipes that come along with them. I’m talking about the kind of recipes you ate as a child, learned to make with your family, and make them for YOUR family every holiday.
Food is such a memory invoker, and tradition is a huge deal to almost everyone on the holidays.
I mean – Thanksgiving is almost upon us. Turkey is.. well, turkey. I’m the girl who sho looks forward to all the Thanksgiving side dishes! That means stuffing, gravy, cranberry sauce, mashed potatoes, fresh rolls and… green bean casserole.
Most Green Bean Casserole recipes involve cream of mushroom soup, but I prefer to make my creamy sauce from scratch. Much better for you, and the taste is far superior!!
Let’s talk about the topping. Now, yes, of course – you could buy the french fried onions from a can and use those (they’re delicious). BUT, what if I was to tell you that you could kick it up a notch and make something BETTER?
We combine onions, flour, salt and panko breadcrumbs and cook them in the oven until crispy and delicious. Then use them as the topping for our Green Bean Casserole.
Why this recipe works
- Adaptable – you can use what you have on hand
- Easy – see my step-by-step instructions (with pictures) below.
Kylee’s Notes & FAQs
Double the recipe for a large crowd!
Storing Leftovers
Store in a covered container for 2-3 days. Reheat in the microwave, or pop in the oven to warm up.
Substitutions/Additions
Thyme. You can use fresh or dried, if you go for fresh, use 2 tsp, dried, just 1 tsp
Beans. You can use fresh green beans instead of frozen. If you use fresh, blanch them in some salted water for a few minutes before adding them to your sauce.
Frozen green beans can be added (thawed and drained) directly the sauce. Avoid canned green beans, they tend to be mushy.
