Ingredients for del monte green bean casserole

Six pantry staples and a canned shortcut transform into nostalgic holiday comfort.

Del Monte green beans are the star here—use the canned variety for convenience, but if you prefer fresh, blanch them first. Costco or Walmart usually have the best prices on the canned beans, and they're pre-trimmed, saving you time. The cream of mushroom soup? Campbell's or Hormel are reliable, but check the ingredients—some brands add fillers. For the fried onions, French's is the classic choice, but any brand works as long as it's not pre-cooked. The key is getting those onions crispy—don't skip the baking step!

No cream of mushroom soup? Substitute with 1.5 cups of milk plus 2 tbsp flour and add 1 tsp onion powder for depth. Running low on sour cream? Greek yogurt works in a pinch, though it's tangier. Want to skip the cheese? Add 2 tbsp extra butter to the topping for richness. The garlic and onion powders are non-negotiable—they're what makes this taste like grandma's version. If you're using fresh green beans, trim the ends and blanch for 2 minutes before mixing. And trust me, whole milk makes the sauce creamier than 2%!

This casserole reheats beautifully—cover with foil and microwave for 2-3 minutes to revive the crisp. Leftovers keep for 4-5 days in the fridge, though it's best eaten within 2. The fried onions lose crispiness over time, so add them fresh when serving. For meal prep, assemble the casserole ahead but bake it just before serving. The topping gets extra crispy when fresh from the oven, so plan ahead for the best texture. Freezes well for up to 3 months—just thaw overnight in the fridge before reheating.

Step-by-step instructions for Del Monte green bean casserole

This classic comfort dish comes together in layers of creamy goodness and crispy crunch.

Drain the 3 cans of Del Monte green beans thoroughly, discarding any liquid. Transfer them to a large mixing bowl and set aside. In a separate medium bowl, whisk together the 2 cans of cream of mushroom soup, 1 cup of milk, 0.5 cup of sour cream, 1 teaspoon of salt, 0.5 teaspoon of black pepper, 0.5 teaspoon of garlic powder, and 0.5 teaspoon of onion powder until completely smooth. This creamy base is the heart of your casserole.

Pour the soup mixture over the drained green beans and gently stir with a rubber spatula until everything is evenly coated. The beans should be fully saturated with the creamy sauce, but don't overmix—just enough to combine. Taste and adjust seasoning if needed, though the soup and spices should be perfectly balanced at this point. This step ensures every bite delivers that signature creamy texture promised in the title.

In a small bowl, melt the 0.5 cup of butter in the microwave for 30-45 seconds, or until completely liquid. Stir in the 0.25 cup of all-purpose flour until smooth—this creates your roux for the topping. In a separate bowl, combine the contents of the 1 package of French fried onions with the melted butter mixture and stir until evenly coated.

If using the optional 1 cup of shredded cheddar cheese, sprinkle it into the mixture and stir until fully incorporated. The topping should have a crumbly, almost paste-like consistency that will crisp beautifully in the oven. This is where the magic happens—the contrast between the creamy filling and crispy topping makes this dish irresistible.

Preheat your oven to 350°F. Transfer the green bean mixture to a greased 9x13-inch baking dish and spread it evenly into a single layer. This is your creamy base, and spreading it evenly ensures consistent baking throughout. The dish should look smooth and well-distributed, with no thick spots that might prevent even cooking.

Spoon the crispy topping mixture evenly over the green beans, pressing down gently with the back of a spoon to help it adhere. The topping should cover the entire surface completely. Bake for 35-40 minutes until the edges are golden brown and the center is bubbling hot. The top should be crispy, while the filling remains creamy—this is the perfect balance of textures you want in every bite.

Remove the casserole from the oven and let it rest for 10 minutes before serving. This resting period allows the filling to set slightly and makes it easier to cut clean slices. The crispy topping will firm up as it cools, creating that satisfying crunch you crave with every forkful.

Serve warm family-style with extra French fried onions sprinkled on top if desired. The creamy green bean filling pairs beautifully with the crispy topping, delivering that nostalgic comfort food experience. Each bite should offer a perfect combination of textures—creamy, crunchy, and perfectly seasoned—making this casserole a true crowd-pleaser.

Wine and beer pairings for del monte green bean casserole

Light White Wine Pairings

A crisp Chardonnay from California's Sonoma Coast—like La Crema—is my go-to pairing. Its bright acidity and subtle buttery notes complement the creamy mushroom sauce beautifully. The wine's citrus undertones also cut through the richness of the fried onions, balancing the dish perfectly.

Serve it slightly chilled (45-50°F) to enhance its refreshing qualities. 🍷

Crisp Lager Balance

For beer lovers, a German Pilsner like Warsteiner or Stella Artois provides the ideal contrast. The crisp, clean malt profile and light carbonation cleanse your palate between bites of creamy casserole.

The subtle hop bitterness also enhances the savory notes in the dish. Avoid heavy ales—they'll overwhelm the delicate flavors. 🍺

Red Wine for Bold Eaters

If you prefer red, a light Pinot Noir from Oregon's Willamette Valley works surprisingly well. Brands like Domaine Serene offer smooth, fruity profiles that won't overpower the dish.

The wine's acidity matches the casserole's creaminess, while its berry notes complement the fried onions. Serve at 60-62°F to preserve its delicate balance. ⚡

Non-Alcoholic Options

For those avoiding alcohol, a sparkling apple cider like Martinelli's adds festive bubbles that mirror the crispy topping's texture. Alternatively, a ginger beer with a splash of lime provides zesty contrast. Both options enhance the dish's comforting qualities without alcohol's intensity. 💫

Seasonal Wine Adaptations

In summer, opt for a Sauvignon Blanc from New Zealand—its herbal notes pair wonderfully with the casserole's savory elements. For winter gatherings, a Viognier with its floral aromas adds warmth to the creamy dish. Each seasonal choice enhances the casserole's nostalgic appeal while adapting to the meal's temperature. 🌟
