Slow Cooker Amish Green Bean Noodle Casserole

Prep Time: 10 minutes
Cook Time: 3–4 hours
Total Time: 3 hours 10 minutes – 4 hours 10 minutes
Servings: 6–8

Ingredients

• 12 ounces wide egg noodles
• 2 (14.5-ounce) cans cut green beans, drained
• 2 (10.5-ounce) cans condensed cream of mushroom soup
• 1½ cups whole milk
• 2 cups crispy fried onions, divided

Instructions

Step 1: Prepare the Slow Cooker

Lightly coat a 4- to 6-quart slow cooker with nonstick cooking spray to prevent sticking and make cleanup easier.

Step 2: Make the Creamy Sauce

In a large mixing bowl, whisk together the cream of mushroom soup and whole milk until smooth and fully combined.

Step 3: Combine the Ingredients

Add the uncooked egg noodles, drained green beans, and 1 cup of the crispy fried onions to the bowl. Stir gently until everything is evenly coated with the creamy sauce.

Step 4: Transfer to Slow Cooker

Pour the mixture into the prepared slow cooker and spread it into an even layer.

Step 5: Slow Cook

Cover and cook on LOW for 3 to 4 hours, or until the noodles are tender and the casserole is hot and bubbly.

Avoid lifting the lid frequently, as this releases heat and extends cooking time.

Step 6: Add the Crispy Onion Topping

Stir the casserole gently to redistribute the sauce.

Sprinkle the remaining 1 cup of crispy fried onions evenly over the top.

Cover and cook on HIGH for 10 to 15 minutes, just until the onions are warmed and slightly crisp.

Step 7: Serve

Serve directly from the slow cooker while hot and creamy.

Tips for Success

• Use wide egg noodles for the best texture.

• Let the casserole sit for 5–10 minutes before serving to allow the sauce to thicken.

Absolutely. Cut fresh green beans into bite-sized pieces and blanch them briefly before adding to the casserole.

Can I freeze this casserole?

Yes, although the noodles may soften slightly after thawing. Freeze in airtight containers for up to 2 months.
