Ingredients for The Ultimate Green Bean Casserole with Potatoes

You’ll be amazed how simple ingredients create something so magical. Here’s what you’ll need:

• 1 lb green beans, trimmed and halved (fresh is best—trust me, you’ll taste the difference)
• 1 lb potatoes, diced into 1/2-inch cubes (Yukon Golds are my go-to for their buttery texture)
• 1 can (10.5 oz) condensed cream of mushroom soup (that little blue can works wonders)
• 1/2 cup milk (whole milk makes the sauce extra creamy, but 2% works in a pinch)
• 1/2 tsp black pepper (freshly cracked if you’ve got it)
• 1/2 tsp garlic powder (the secret flavor booster)
• 1/2 tsp onion powder (don’t skip this—it adds depth)
• 1 cup fried onions (reserve some extra for sprinkling—I always do!)
• 1 tbsp butter, cut into little dots (because everything’s better with butter)

See? Nothing fancy—just good, honest ingredients that come together beautifully. Now let’s make some magic!

How to Make The Ultimate Green Bean Casserole with Potatoes

Okay, let’s get cooking! This casserole comes together so easily, but I’ve got a few tricks to make sure it’s perfect every time. Just follow these simple steps, and you’ll have everyone raving about your cooking skills.

Prep the Vegetables

First things first—let’s tackle those veggies. Bring a big pot of salted water to boil for the potatoes. I like to dice them into 1/2-inch cubes so they cook evenly. Give them about 10 minutes—you want them just tender enough to pierce with a fork but not falling apart. Drain them well and set aside.

While the potatoes are cooking, blanch the green beans in another pot of boiling water. Just 3 minutes is all they need—this keeps that beautiful bright green color and crisp-tender bite. Shock them in ice water if you’re fancy, but honestly, I just drain and let them hang out until mixing time.

Mix the Sauce

Now for the magic glue that holds everything together! In a medium bowl, whisk together the cream of mushroom soup, milk, black pepper, garlic powder, and onion powder. Really get in there and mix it well—you want all those spices evenly distributed so every bite is packed with flavor.

Assemble and Bake

Grab your favorite 9×13 inch baking dish (a 3-quart casserole dish works great too). Toss in the drained potatoes and green beans, then pour that luscious sauce over everything. Use a big spoon to gently mix it all together—don’t be shy!

Now the fun part: sprinkle those crispy fried onions evenly over the top. I always sneak a handful to snack on while I’m cooking! Dot the top with little bits of butter—this helps the onions get extra golden and delicious.

Pop it in your preheated 350°F oven for about 25 minutes. You’ll know it’s ready when the edges are bubbling and the top is golden brown. The smell will have everyone hovering around the kitchen—trust me!

Tips for Perfect The Ultimate Green Bean Casserole with Potatoes

After making this casserole more times than I can count, I’ve picked up some foolproof tricks to make it absolutely perfect every time:

• Fresh is best: While frozen green beans work in a pinch, fresh ones give that perfect crisp-tender texture. Just trim the ends and snap them in half—it’s worth the extra few minutes!
• Soup swap: Not a mushroom fan? No problem! Cream of chicken or celery soup works beautifully too. Just keep that same 10.5 oz can size.
• Double the crunch: Reserve some extra fried onions to sprinkle on right before serving—that second layer stays extra crispy!
• Let it rest: Wait 5 minutes after baking (if you can resist!). This lets the sauce thicken up perfectly for serving.

Little tweaks make all the difference—this is how you turn great into absolutely unforgettable!

Serving Suggestions for The Ultimate Green Bean Casserole with Potatoes

This casserole is like the ultimate team player—it makes everything around it taste better! On holidays, I love pairing it with glazed ham or a juicy roasted turkey (hello, Thanksgiving superstar!). For Sunday dinners, it’s perfect alongside garlic butter chicken or a standing rib roast. And don’t forget—it’s hearty enough to stand alone with just a crisp salad for a satisfying vegetarian meal. Pro tip: serve it straight from the oven when those onions are at their crispiest!

Storing and Reheating The Ultimate Green Bean Casserole with Potatoes

Leftovers? Ha! Just kidding—I know they’re rare with this dish, but if you’re lucky enough to have some, here’s how to keep them tasting amazing. Cover tightly with foil or transfer to an airtight container and refrigerate for up to 3 days. When reheating, skip the microwave (soggy onions = sad day). Instead, warm it in a 300°F oven for about 15-20 minutes until heated through. The onions won’t be quite as crisp, but the flavors meld even more deliciously!

FAQs About The Ultimate Green Bean Casserole with Potatoes

I get asked these questions all the time—here are my tried-and-true answers to help you make this casserole your own:

Can I use frozen green beans?
Absolutely! Just thaw them completely first and pat them dry—this prevents extra water from making the casserole soggy. The texture will be a bit softer than fresh, but still delicious.

Can I make it ahead?
You bet! Assemble everything (right up to adding the fried onions), cover tightly, and refrigerate for up to 24 hours. When ready, sprinkle the onions on top and bake—just add 5-10 extra minutes since it’s going in cold.

How to make it gluten-free?
Easy swap! Use gluten-free cream of mushroom soup (or make your own) and check that your fried onions are GF. I love the crispy gluten-free onion varieties now available—they work perfectly!
