How to make Trader Joe’s green bean casserole?

To make this casserole, we’re first sauteing onion and garlic and stir-frying the green beans with a few fresh mushrooms. That’s healthy already, and you’ll love the smell filling your kitchen.

The next step is simmering the whole thing with cream of mushroom, also from Trader Joe’s, of course, that’s the casserole filling. 

When topped with lots of cheese and grated in the oven, you get that picture-perfect, golden casserole with the creamiest texture and the gooiest surface.

When to serve Trader Joe’s green bean casserole?

Making this recipe from start to finish takes about an hour, but half the time is letting the casserole cook in the oven. 

That means that you’ll only be cooking for around 15 minutes, and that makes this dish perfect for when you have little time to cook but still want to nurture your family with a traditional home-cooked meal.

Yes, this one is sloppy and cheesy and perhaps not what you’d serve at a fancy dinner party, but trust me, it’s perfect for weeknight dinners with the family. 

The best part? Leftovers are even tastier than freshly made, which means you want to leave some casserole for tomorrow’s lunch. Let’s make ourselves a veggie casserole!
