Ingredients for Green Bean Casserole Recipe with Bacon and Cheese
Restaurant-quality ingredients create this elevated casserole with rich, smoky, and creamy layers.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Green Beans 🌿 | 1 ½ lb | Trimmed, cut into 2-inch pieces |
| Thick-Cut Bacon 🥓 | 8 oz | Smoked, chopped into 1/2-inch pieces |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded from block |
| French Fried Onions 🧅 | 1 ½ cups | Canned, for topping |
| Heavy Cream 🥛 | 1 cup | Full-fat for creaminess |
| Whole Milk 🥛 | ½ cup | For sauce consistency |
| All-Purpose Flour 🌾 | 2 tbsp | For sauce thickening |
| Unsalted Butter 🧈 | 2 tbsp | For roux base |
| Garlic Cloves 🧄 | 3 cloves | Minced for sauce |
| Yellow Onion 🧅 | ½ whole | Finely diced for sauce |
| Chicken Broth 🍲 | ½ cup | Low-sodium preferred |
| Dijon Mustard 🟡 | 1 tbsp | For depth of flavor |
| Worcestershire Sauce 🍶 | 1 tsp | Adds umami richness |
| Kosher Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | For seasoning layers |
The bacon and cheese are non-negotiable for depth of flavor. Opt for thick-cut smoked bacon from a reputable butcher or Whole Foods for consistent marbling. For the cheddar, block cheese shredded at home melts more smoothly than pre-shredded (which contains anti-caking agents). Fresh green beans should be bright green and snappy—avoid limp or yellowing pods. The French fried onions must be the classic Durkee or French’s brand for that perfect crunch.
Need to make it ahead? The casserole can be assembled (minus the fried onion topping) and refrigerated for 24 hours before baking. For a lighter version, half-and-half can replace the heavy cream. No cheddar? Gruyère or Monterey Jack melt beautifully. If you must skip the bacon, smoked paprika adds a similar depth, though the texture won’t be the same. The Worcestershire sauce is key—Lea & Perrins is the standard.
Bake and serve immediately for the best texture. Leftovers keep in the fridge for 3-4 days, though the fried onions lose their crispness. Reheat covered with foil at 350°F for 15-20 minutes. This dish does not freeze well due to the dairy and fried onion components.

Step-by-Step Instructions for Green Bean Casserole With Bacon and Cheese
Master the technique for a dish with perfect texture and layered flavors every time.
Step 1: Blanch and Shock the Fresh Green Beans
Bring a large pot of salted water to a rolling boil. Add all 1.5 lb Fresh Green Beans and cook for 3-4 minutes until bright green and tender-crisp. The beans should bend slightly but not snap when tested.
Immediately drain and plunge into a bowl of ice water to stop the cooking process. This preserves the vibrant color and crisp texture. Drain again and pat dry thoroughly with a clean kitchen towel. Set aside.
Step 2: Render the Bacon and Sauté Aromatics
In a large skillet over medium heat, cook all 8 oz Thick-Cut Bacon until crispy and golden brown, about 8-10 minutes. Transfer the bacon to a paper towel-lined plate, reserving 2 tablespoons of the rendered fat in the pan.
In the same skillet, add 0.5 whole Yellow Onion (finely diced) and cook for 3-4 minutes until translucent and soft. Add all 3 cloves Garlic Cloves (minced) and cook for 30 seconds until fragrant. Remove from heat and set aside.
Step 3: Create the Creamy Cheese Sauce
In a medium saucepan, melt all 2 tbsp Unsalted Butter over medium heat. Whisk in all 2 tbsp All-Purpose Flour to form a smooth roux. Cook for 1 minute, stirring constantly, until light golden brown.
Gradually whisk in 1 cup Heavy Cream, 0.5 cup Whole Milk, and 0.5 cup Chicken Broth until smooth. Stir in 1 tbsp Dijon Mustard, 1 tsp Worcestershire Sauce, 1 tsp Kosher Salt, and 0.5 tsp Freshly Ground Black Pepper.
Bring to a simmer and cook for 3-4 minutes until the sauce thickens enough to coat the back of a spoon. Remove from heat and stir in 1.5 cups of the 2 cups Sharp Cheddar Cheese until fully melted and smooth.
Step 4: Assemble and Bake the Casserole
In a large bowl, combine the blanched Fresh Green Beans, crispy Thick-Cut Bacon, sautéed onion and garlic mixture, and the cheese sauce. Stir gently to coat everything evenly. Transfer to a greased 9×13-inch baking dish.
Sprinkle the remaining 0.5 cup Sharp Cheddar Cheese evenly over the top. Bake in a preheated 375°F oven for 15 minutes until bubbly and lightly golden.
Step 5: Add the Crunchy Topping and Finish
Remove the casserole from the oven and sprinkle all 1.5 cups French Fried Onions evenly over the top. Return to the oven and bake for an additional 5-8 minutes until the onions are deep golden brown and crispy.
Let the casserole rest for 5 minutes before serving. This allows the sauce to set slightly and makes it easier to portion. The final dish should have creamy beans, smoky bacon, and a crispy, cheesy topping in every bite.
Pro Tips For Making Green Bean Casserole Recipe With Bacon And Cheese
- Blanch the Beans: Toss fresh green beans in boiling salted water for 3 minutes then shock in ice water—I learned this the hard way after serving sad, squeaky beans that never softened in the casserole.
- Render Bacon First: Cook the thick-cut bacon until crisp, then use that fat to sauté the onions (yes, the fried ones too) for a depth of flavor you can’t get from raw bacon bits.
- Skip Pre-Shredded Cheese: Grate the sharp cheddar yourself; the anti-caking agents in pre-shredded cheese make the sauce grainy instead of velvety.
- Crisp Onions Last: Sprinkle half the French fried onions in the middle of baking and the rest in the last 5 minutes—this keeps them from turning into sad, soggy bits.
Pro Cooking Tips for Great green bean casserole recipe with bacon and cheese
Perfect Bean Texture
Blanching the 1.5 lb Fresh Green Beans for exactly 3-4 minutes is crucial. Undercook and they’ll be raw; overcook and they turn mushy. The ice bath stops cooking immediately, preserving that perfect crisp-tender bite. I use a slotted spoon to transfer beans to avoid splashing hot water. 💡
Bacon Crispness
Cook the 8 oz Thick-Cut Bacon over medium heat to render fat slowly. This ensures even crisping without burning. Reserve 2 tbsp of that golden fat for sautéing onions—it adds incredible smoky depth to your sauce.
Sauce Consistency
Your roux needs 1 minute of cooking to eliminate the raw flour taste. Whisk constantly as you add liquids to prevent lumps. I use a flat whisk for better contact with the pan. The sauce should coat a spoon but still drip slowly.
Cheese Melting
Always shred your own Sharp Cheddar Cheese from a block. Pre-shredded contains anti-caking agents that prevent smooth melting. Remove the sauce from heat before adding cheese to prevent separation. Stir until just combined.
Topping Timing
Add the 1.5 cups French Fried Onions only in the final 5-8 minutes. Any longer and they’ll lose their signature crunch. Watch closely—when they turn deep golden, pull the dish immediately. 🔥
Resting Period
That 5-minute rest isn’t just for show. It lets the sauce thicken slightly so it doesn’t run off when serving. I tent with foil to keep it warm while the cheese sets beautifully.

Frequently Asked Questions
Can I use canned green beans instead?
Yes, but drain and rinse them well first. Canned beans are softer, so reduce the baking time by 5 minutes to prevent mushiness. Fresh is preferred for better texture.
What if my cheese sauce is too thick?
Whisk in warm milk, 1 tablespoon at a time, until it reaches a smooth, pourable consistency. Avoid overheating, as this can cause the cheese to separate.
Can I make this ahead of time?
Assemble the casserole (without fried onions) and refrigerate for up to 24 hours. Add the topping and bake as directed when ready. Avoid freezing, as it affects texture.
How do I keep the fried onions crispy?
Add them only during the final 5-8 minutes of baking. Watch closely to prevent burning, as they crisp quickly under high heat.
