Cheesy Creamed Green Beans are the type of dish I bring to gatherings when I want to see everyone reach for seconds and ask for the recipe on the spot. This green bean casserole delivers a golden cheesy top layer with a creamy yet tangy sauce under a crisp and savory finish of bacon and cornflakes. Whether you are setting a weeknight table or prepping for a large holiday feast this comforting side never fails to get attention.
Every holiday at my house includes this casserole because it disappears fast My son loves the crispy edges and my husband requests it for every Thanksgiving
Ingredients
- Butter: Softens onions and helps build the cream sauce Choose good quality for best flavor
- Onion: Adds savory flavor A fresh onion finely chopped makes a big difference
- Garlic: Brings aromatic depth Use fresh cloves or preminced for convenience
- Flour: Thickens the sauce creating luscious creaminess Allpurpose flour works well
- Frozen Green Beans: I prefer french style for tenderness Make sure to thaw and drain so the sauce is not watery
- Salt pepper nutmeg: Nutmeg may sound odd but it enhances the creaminess without being overpowering Use just a pinch of fresh grated if you have it
- Sour Cream: Delivers tangy rich sauce Opt for full fat for maximum flavor
- Bacon Bits: Choose thick cut bacon for more flavor or ready made for ease
- Shredded Cheese: Cheddar melts beautifully but try colby jack if you want variety Choose blocks you shred yourself for best meltability
- Cornflakes: Provide the signature crunch Look for plain unsweetened types for a savory finish
- Parmesan: Freshly shredded over the top right before serving adds umami and salinity
Step-by-Step Instructions
- Get the Oven and Baking Dish Ready:
- Preheat your oven to four hundred degrees Fahrenheit and gently grease a one quart baking dish with a little oil or spray to prevent sticking
- Sauté the Aromatics:
- Melt a tablespoon of butter in a large skillet over medium heat Add chopped onions and garlic Cook for two minutes stirring often until onions are becoming soft and fragrant
- Cook the Beans:
- Add thawed well drained green beans to the pan with the onions and garlic Stir and cook for four minutes so the beans absorb flavor and any excess moisture cooks off
- Create the Roux:
- Push the beans to the sides of the skillet Add another tablespoon of butter in the center Let it melt Sprinkle in the flour salt pepper and nutmeg Stir everything together and cook for one minute to remove any raw flour taste This step ensures your sauce is velvety smooth
- Stir in Sour Cream:
- Add in all the sour cream Stir well so every bean is coated in the creamy sauce Let it gently bubble for one to two minutes to heat through and meld flavors
- Assemble the Casserole:
- Transfer the creamed green bean mixture to your prepared baking dish Sprinkle bacon bits and shredded cheese evenly over the top Melt your remaining butter and toss it with crushed cornflakes Scatter this mixture all over for a generous crunchy layer
- Bake the Casserole:
- Place the dish in the oven Bake for twenty minutes or until the top is deeply golden and the edges are bubbling If the cornflakes brown quickly cover loosely with foil halfway through for perfect crispy texture
- Finish and Serve:
- Remove from oven Let cool a couple of minutes Before serving grate fresh parmesan over the top The casserole is ready to be enjoyed warm

I have always loved how the touch of nutmeg rounds out the richness in the sauce My grandmother would add it to almost every creamy holiday dish and now it is my secret to getting that classic flavor
