Ingredients for cracker barrel green bean casserole copycat
Twelve ingredients transform into that iconic Cracker Barrel green bean casserole with crispy topping and creamy mushroom sauce.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Green Beans 🥦 | 1 ½ lb | Trimmed, cut into 2-inch pieces |
| Yellow Onions 🧅 | 2 medium | Thinly sliced for crispy topping |
| Cream of Mushroom Soup 🍄 | 2 cans | Condensed, 10.5 oz each |
| Milk 🥛 | 1 cup | Whole milk for creaminess |
| Butter 🧈 | ½ cup | Unsalted, melted |
| All-Purpose Flour 🌾 | ½ cup | For thickening sauce |
| Fresh Mushrooms 🍄 | 8 oz | Sliced, for added texture |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | For extra depth |
| French Fried Onions 🧅 | 1 cup | For final crunchy layer |
| Shredded Cheese 🧀 | 1 cup | Cheddar or American blend |
The onions are the secret to that signature crunch. Use medium yellow onions—they're sweet and crisp when sliced thin. Most grocery stores carry them year-round, but check the produce section for the freshest ones. Trader Joe's and Costco often have pre-sliced options, but slicing them yourself ensures maximum crispiness. For the mushrooms, cremini or white button work best—their mild flavor lets the cream of mushroom soup shine. If you can't find fresh mushrooms, canned mushrooms drained well will do in a pinch, though texture differs slightly.
No cream of mushroom soup? Make your own by blending cooked mushrooms, chicken broth, and a splash of cream. The French fried onions can be swapped for crushed potato chips or panko if you're in a bind, though the flavor won't be identical. For the cheese, sharp cheddar adds more depth than mild cheddar. The green beans should be bright green and crisp—avoid any that feel rubbery or yellowed. If you can't find fresh, frozen green beans thawed and drained well work perfectly. The butter should be unsalted to control the seasoning.
This casserole reheats beautifully—just cover with foil and warm in the oven. Keeps in the fridge for 4-5 days and freezes for 3 months. For the crispiest topping, broil the onions for 2-3 minutes at the end. I always make a double batch—half for dinner, half for leftovers that taste even better the next day. Store in an airtight container to maintain crispiness.

Step-by-step instructions for Cracker Barrel green bean casserole copycat recipe
Here's how to recreate that iconic restaurant version with perfect texture balance every time.
Prepare the Green Beans and Mushroom Mixture
Preheat your oven to 375°F. Trim the ends from the 1.5 lb fresh green beans and cut them into 2-inch pieces. Spread them on a baking sheet and toss with 1 teaspoon salt and ½ teaspoon black pepper. Roast for 10 minutes until just tender but still bright green—this preserves their color while developing flavor.
While the beans roast, slice the 8 oz fresh mushrooms into thin pieces. In a large skillet over medium heat, melt the ½ cup butter and sauté the mushrooms for 5-6 minutes until they release their moisture and begin to brown. Add the ½ teaspoon garlic powder and cook for another 1 minute, stirring constantly. Remove from heat and set aside.
Make the Creamy Mushroom Sauce
In a separate bowl, whisk together the 2 cans cream of mushroom soup, 1 cup milk, and ½ cup all-purpose flour until smooth. This creates a roux that will thicken beautifully when combined with the hot mushrooms. Pour this mixture into the skillet with the mushrooms and stir over medium-low heat for 3-4 minutes until it thickens slightly and coats the back of a spoon.
Add the roasted green beans to the sauce and stir gently to combine. The beans should be fully coated in the creamy mixture. Transfer this entire mixture to a 9x13-inch baking dish, spreading it evenly. This layer forms the heart of your casserole—creamy, flavorful, and perfectly textured.
Assemble the Crispy Topping
Thinly slice the 2 medium yellow onions into rings. In a small bowl, toss them with 1 tablespoon melted butter (reserved from earlier) until evenly coated. Spread the onion rings evenly over the green bean mixture, pressing down lightly to ensure they make contact with the creamy layer below.
Sprinkle the 1 cup shredded cheese evenly over the onions. This cheese will melt and create a golden, slightly crispy blanket when baked. Finally, scatter the 1 cup French fried onions over the top—these will provide the signature crunch that makes this casserole so special.
Bake to Golden Perfection
Place the baking dish on the middle rack of your preheated oven and bake for 25-30 minutes until the top is golden brown and bubbly. The cheese should be fully melted with a crispy texture on top, while the onions become caramelized and crunchy. You'll know it's done when the edges are slightly browned and the filling is heated through.
Let the casserole rest for 10 minutes before serving. This resting period allows the layers to set slightly, making it easier to slice and serve without losing the crispy topping. The contrast between the creamy green bean mixture and the crispy, cheesy top is what makes this dish so iconic—don't skip this step!
Pro Tips For Making Cracker Barrel Green Bean Casserole Copycat
- Blanch Beans First: Dump raw green beans straight into the oven, and you’ll end up with a mushy, sad casserole. Blanch them for 3-4 minutes in boiling salted water first—crisp-tender beans hold up better, and the texture stays right. Drain well and shock in ice water to stop cooking; this step is non-negotiable if you want that classic Crunchy Onion topping to work its magic.
- Sauté Onions Low: After burning three batches of onions into bitter oblivion, I finally learned: low heat is your friend. Cook those yellow onions in butter until soft and translucent—not golden, not caramelized—just sweet and barely tender. Overcooking turns them into flavor bombs that overpower the whole dish. Keep the heat at a simmer, and stir occasionally.
- Mix Sauce Last: Stir the cream of mushroom soup and milk into the beans after they’ve roasted for 15 minutes. Why? The beans release moisture, and adding the sauce too early turns your casserole into a watery swamp. Toss it in during the last 10 minutes of baking so the sauce thickens properly and clings to the beans instead of pooling at the bottom.
- Toast the Topping: Skip the microwave shortcut for the fried onion topping—it’s so much better when you crisp it fresh. Heat a dry skillet over medium-high, add the onions (with a pinch of salt), and stir constantly until they’re golden and sizzling. Sprinkle them over the casserole right before serving, so they stay crunchy and not soggy. Yes, it takes 5 minutes, but it’s worth it.

Frequently asked questions
Why does the Cracker Barrel version have such a crispy topping?
The secret lies in the two-step baking process and ingredient choices. First, they use thinly sliced yellow onions that caramelize beautifully. Second, they broil the casserole for the final 2-3 minutes to create that signature golden, crispy texture. The French fried onions on top add an extra crunch layer that stays crisp even when served.
Can I make this casserole ahead of time?
Assemble the dish up to 24 hours ahead and refrigerate uncovered. When ready to bake, add the French fried onions and broil for 5-7 minutes at the end to restore crispiness. For make-ahead leftovers, cover with foil and reheat at 350°F for 15-20 minutes. The flavors actually improve after resting overnight.
What's the best way to reheat leftovers?
For best results, cover with foil and reheat at 350°F for 15 minutes, then uncover and broil for 2-3 minutes to crisp the onions. Microwaving works in a pinch (cover with a damp paper towel for 1-2 minutes), but the texture won't be as perfect. The oven method preserves that creamy-mushroom contrast.
Can I substitute frozen green beans?
Yes, but with adjustments. Use 2 cups frozen green beans (thawed and drained well) instead of fresh. For extra flavor, sauté them with 1 teaspoon butter and ½ teaspoon garlic powder for 3-4 minutes before mixing with the creamy sauce. This helps compensate for their milder flavor compared to fresh.
How do I keep the onions extra crispy?
For maximum crunch, broil the casserole uncovered for the last 2-3 minutes of baking. Also, press the onions firmly into the creamy layer before baking so they make direct contact with the heat source. If using store-bought French fried onions, look for the "extra crispy" variety in the baking aisle.
