Ingredients for mccormick green bean casserole

Sixteen ingredients transform into the iconic holiday comfort dish everyone craves.

The McCormick cream of mushroom soup is non-negotiable for authentic flavor—grab the 10.5 oz cans from the soup aisle, not the condensed version. Fresh green beans should be bright green and crisp, not wilted or rubbery. For the potato chips, plain, crispy varieties work best—Lay's Classic or Ruffles are reliable choices. The yellow onion needs to be medium-sized; smaller onions won’t yield enough volume. Garlic cloves should be fresh, not dried or powdered, for that aromatic depth. Unsalted butter is preferred here to control the seasoning balance, and Diamond Crystal kosher salt dissolves more easily than table salt, ensuring even distribution throughout the casserole.

No heavy cream? Half-and-half or whole milk will work, though the texture will be slightly lighter. Substituting the cream of mushroom soup with homemade requires 2 cups sautéed mushrooms, 1/4 cup flour, and 2 cups milk—but the canned version is far more convenient and delivers consistent results. French fried onions can be omitted if you prefer a cleaner look, but they add a delightful crunch. Sharp cheddar cheese enhances the richness; Parmesan works too but leans more savory. For the potato chips, if you can’t find plain, salted chips will work—just reduce the added salt by half. Fresh parsley is ideal, but dried parsley at one-third the amount suffices in a pinch.

This casserole reheats beautifully—cover with foil and bake at 350°F for 15-20 minutes to restore crispiness. It keeps well in the fridge for up to 4 days, though the potato chip topping loses crunch over time. For make-ahead convenience, assemble the casserole a day in advance and refrigerate uncovered—this helps the chips crisp up better when baked. Portion into individual baking dishes for easy serving, and garnish with extra French fried onions right before serving to maintain that restaurant-quality presentation. Leftovers freeze for up to 3 months when stored in an airtight container.

Step-by-step instructions for McCormick green bean casserole

Here's how to achieve that perfect balance of crispy potato chip topping and velvety mushroom sauce.

Trim the ends from the 2 lbs of fresh green beans and cut them into 2-inch pieces. Spread them evenly in a large pot and cover with cold water by about 1 inch. Bring to a boil over medium-high heat and cook for exactly 3 minutes—they should be bright green but still crisp with a slight bite. Drain immediately in a colander and rinse under cold water to stop the cooking process. This blanching removes any bitterness and ensures tender-crisp beans that won't turn mushy in the oven.

Transfer the blanched green beans to a large mixing bowl and set aside. I like to work quickly here because green beans continue cooking even after being removed from boiling water. The key is to get them cooled down fast with that cold water rinse—this preserves their vibrant color and texture for the final dish.

In a separate large bowl, combine the 2 cans of cream of mushroom soup, 0.5 cup of milk, 0.25 cup of heavy cream, and 0.5 cup of melted butter. Whisk vigorously until completely smooth—this ensures no lumps in your sauce. The heavy cream adds that luxurious richness promised in the title, while the butter contributes depth of flavor. Add the 2 tbsp of all-purpose flour and whisk again until fully incorporated. This creates a roux that will thicken beautifully during baking.

In a small skillet, melt 2 tbsp of butter over medium heat. Add the finely diced 1 whole yellow onion and minced 3 cloves garlic, cooking for 3-4 minutes until softened but not browned. This aromatic base forms the flavor foundation of your casserole. Transfer the onion-garlic mixture to the soup mixture and stir well. Season with the 1 tsp salt and 0.5 tsp black pepper, then fold in the prepared green beans until everything is evenly coated.

Transfer the green bean mixture to a greased 9x13-inch baking dish, spreading it evenly into a single layer. This even distribution is crucial for consistent baking. Preheat your oven to 375°F while you prepare the topping. The baking dish should be placed on the middle rack to ensure even heat circulation throughout the baking process.

Crush the 1 bag of potato chips coarsely between your fingers—you want a mix of small chunks and fine crumbs. Sprinkle this evenly over the green bean mixture, pressing down gently to help it adhere. This step creates that signature crispy texture that makes this casserole special. Top with the 0.5 cup sharp cheddar cheese and 0.25 cup french fried onions, distributing them evenly across the surface.

Bake uncovered for 25-30 minutes until the edges are bubbly and the top is golden brown with crispy potato chip pieces. The cheese should be melted and slightly browned in spots. I recommend checking at the 25-minute mark—every oven runs slightly differently, and you want that perfect balance of crispy topping without burning.

Remove from the oven and let rest for 5 minutes before serving. This resting period allows the casserole to set slightly, making it easier to slice and serve. The final result should be tender green beans in a rich, creamy mushroom sauce with a satisfying crunch from the potato chip topping. Sprinkle with the 1 tbsp dried parsley just before serving to add that fresh, vibrant finish that elevates the dish.

Wine and beer pairings for this dish

Classic White Wine

This creamy, cheesy casserole pairs beautifully with a crisp Chardonnay from California’s Napa Valley or a buttery Burgundy from France. The acidity in these wines cuts through the richness of the cream sauce while complementing the earthy mushroom notes.

I love a Meursault from Burgundy—its nutty, citrusy profile balances the dish’s creaminess perfectly. Serve it slightly chilled to let the wine’s brightness shine against the warm casserole. 🍷

Light-Bodied Red

For those who prefer red wine, a Pinot Noir from Oregon’s Willamette Valley offers a delicate yet robust match. Its red fruit notes and subtle earthiness won’t overpower the green beans or mushroom sauce.

Look for a Pinot Noir with 12-13% ABV—lighter-bodied wines like Domaine Serene or La Crema work beautifully. Avoid heavy reds like Cabernet Sauvignon, as they’ll clash with the dish’s creamy texture. 🍇

Beer Pairings

A honey lager like Allagash White or Sierra Nevada Pale Ale complements the casserole’s sweet and savory flavors. The honey notes in the beer mirror the caramelized edges of the potato chip topping, while the pale ale’s hoppy bitterness balances the creaminess.

For a darker option, try a wheat beer with a touch of spice—Blue Moon adds a refreshing contrast. Serve the beer slightly cooler than room temperature for the best pairing experience. 🍺

Non-Alcoholic Options

If alcohol isn’t an option, a sparkling apple cider like Martinelli’s or a ginger beer like Brew Dr. Brown’s adds a festive touch. The effervescence cleanses the palate between bites, while the apple’s sweetness enhances the casserole’s creamy notes.

For a more savory pairing, try a sparkling water with lemon—it’s refreshing and lets the dish’s flavors stand out. 🍎

Seasonal Wine Upgrades

For holiday gatherings, consider a late-harvest Riesling from Germany or a Vin Santo from Italy. These dessert wines add a sweet contrast to the savory casserole, making them perfect for Thanksgiving or Christmas.

Their honeyed notes complement the caramelized potato chips beautifully. Serve these wines slightly warmed to enhance their aromatic qualities. 🍷✨
