Ingredients

Here’s the ingredient list for The Ultimate Green Bean Casserole with Potatoes. I keep measurements exact so you can print once and go. This lineup supports a creamy, cozy win that fits busy weeknights.

• 3 cups fresh green beans, trimmed and cut in half — crisp, bright bites that hold up under creamy sauce
• 3 medium potatoes, peeled and diced — starchy chunks that soak up flavor
• 1 small onion, finely chopped — adds sweetness and a savory base
• 2 cloves garlic, minced — quick aroma boost
• 1 cup sliced mushrooms (optional) — earthy depth when you want it
• 1 1/2 cups milk (or dairy-free alternative) — creamy base; switch to almond or oat milk if needed
• 2 tbsp cornstarch mixed with 2 tbsp water — slurry to thicken the sauce without lumps
• 1 cup shredded cheddar cheese (or dairy-free cheese) — melty, comforting finish or dairy-free swap
• 1 tsp salt — enhances every flavor note
• 1/2 tsp black pepper — gentle heat
• 1 tsp paprika — smoky warmth
• 1 cup crispy fried onions (gluten-free if needed) — topping with crunch
• 2 tbsp olive oil — for sautéing aromatics and keeping veggies glossy

Notes: For a richer base, heavy cream can replace milk (thin with a splash of water if needed). Fresh green beans deliver the best texture, though canned can work with a slightly longer simmer. Gluten-free fried onions keep it gluten-free. A dairy-free version uses dairy-free milk and cheese. Exact quantities appear at the bottom of the article for easy printing.

How to Make The Ultimate Green Bean Casserole with Potatoes

Step 1: Prep and preheat

I preheat the oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish. This helps the casserole bake evenly and prevents sticking.

Step 2: Parboil potatoes

I boil the diced potatoes in salted water for 8–10 minutes until just tender. Then I drain and set them aside so they’ll soften further in the casserole without turning mushy.

Step 3: Prepare the green beans

I steam or blanch the green beans for about 5 minutes. Then I rinse under cold water to stop cooking and lock in bright color and crisp-tender texture. Tip: for best color, shock them in ice water after blanching.

Step 4: Sauté aromatics

I heat olive oil in a large skillet over medium heat. I add onions, garlic, and mushrooms if using, and sauté until softened and fragrant.

Step 5: Make the creamy sauce

I stir in milk, salt, pepper, and paprika. I slowly whisk in the cornstarch slurry and cook until the sauce thickens to a creamy coating that clings to the veggies. This is where The Ultimate Green Bean Casserole with Potatoes really starts to come together.

Step 6: Combine and bake

I fold in the cooked potatoes, green beans, and half of the cheese. I transfer the mixture to the prepared dish, sprinkle the remaining cheese on top, and bake for 20 minutes.

Step 7: Finish and rest

I remove the dish from the oven, top with crispy fried onions, and bake 5–7 minutes more until the top is golden. I let the casserole rest about 5 minutes before serving for clean slices.

Tips for Success

• I use fresh green beans for the best texture; if using canned beans, drain well and reduce steam time. For contrast.
• For extra creaminess, whisk in a little more milk, then fold in the cornstarch slurry gradually. I often whisk in a splash of stock.
• Bake uncovered for a crisp, golden top; cover briefly if the top browns too fast. The top browns beautifully.
• Dairy-free option: use dairy-free milk and cheese, and gluten-free fried onions. There are plenty of dairy-free options.

Equipment Needed

• 9×13-inch baking dish (or any large casserole dish)
• Large skillet (or wide sauté pan)
• Medium saucepan for potatoes (or small pot)
• Whisk for the sauce (or sturdy spoon)
• Measuring cups and spoons (or a kitchen scale)
• Optional: colander and steamer basket (or slotted spoon)
• Heatproof spatula or wooden spoon

Variations

• Dairy-free version: I use dairy-free milk and cheese, plus dairy-free fried onions.
• Gluten-free version: I stick with gluten-free fried onions and certified gluten-free ingredients.
• Add protein: I toss in diced cooked chicken or crumbled bacon (adjust salt).
• Herb lift: I love fresh thyme or chives for brightness.
• Spice twist: I add a pinch of chili flakes for a subtle kick.

Make-Ahead and Storage for The Ultimate Green Bean Casserole with Potatoes

Make-ahead weeknights save me as a busy home cook. The Ultimate Green Bean Casserole with Potatoes shines even when prepared ahead. Here’s how I prep, store, and reheat with ease to keep flavor intact.

• Make ahead: Assemble unbaked up to 24 hours in advance; refrigerate and bake when ready. If you bake straight from the fridge, add about 5–10 minutes to the bake time.
• Smart prep: Chop onions and garlic, parboil potatoes, and blanch beans earlier in the day; store each component separately for quick assembly.
• Top crunch: Keep the crispy fried onions separate and add just before baking to preserve their crispiness.

The Ultimate Green Bean Casserole with Potatoes stores beautifully in the fridge. Leftovers will stay good for 3–4 days in an airtight container. Reheat gently in the oven until hot and bubbling, or use the microwave if you’re in a hurry.

• Freezing options: Freeze baked casserole for up to 2 months. For best texture, freeze unbaked after assembly and thaw overnight in the fridge before baking.
• Thawing tip: If you’re thawing, add extra 5–15 minutes to the bake time to heat through evenly.
• Dairy-free note: Dairy-free versions freeze well; use dairy-free milk and cheese and keep fried onions gluten-free if needed.

Reheating guidance keeps the dish tasting fresh. In the oven, bake at 350°F (175°C) until hot and bubbling, covered if the top browns too quickly. In a hurry? The microwave works, but I prefer the oven for that cozy, crisp top.
