Midwest Green Bean and Tater Tot Casserole

This hearty baked casserole is a beloved fixture of midwestern church potlucks, family reunions, and weeknight dinners across states like Minnesota, Wisconsin, and Ohio. It marries the classic green bean casserole tradition — popularized in the 1950s — with the crispiness of tater tots, a beloved regional pantry staple that creates an irresistible golden crust.

Serves: 8

Ingredients

• 900g (2 lb) fresh green beans, trimmed and cut into 5cm (2-inch) pieces (or 3 x 400g / 14 oz cans, drained)
• 2 tbsp (30g) unsalted butter
• 1 medium yellow onion, diced
• 3 cloves garlic, minced
• 250g (9 oz) white mushrooms, sliced
• 3 tbsp (25g) all-purpose flour
• 480ml (2 cups) whole milk
• 240ml (1 cup) chicken or vegetable broth
• 120g (4 oz) cream cheese, softened
• 1 tsp Worcestershire sauce
• 1 tsp onion powder
• ½ tsp smoked paprika
• Salt and black pepper to taste
• 900g (2 lb) frozen tater tots
• 150g (1.5 cups) sharp cheddar cheese, shredded
• 2 tbsp fresh chives, chopped, to garnish

Instructions

1. Preheat oven to 200°C (400°F). Grease a 33 x 23cm (13 x 9-inch) baking dish.
2. If using fresh green beans, blanch in boiling salted water for 4 minutes, then drain and plunge into ice water to stop cooking. Drain well and pat dry.
3. Melt butter in a large skillet over medium-high heat. Add onion and cook for 5–6 minutes until softened. Add garlic and mushrooms and cook for 7–8 minutes until the mushrooms release their liquid and it evaporates.
4. Sprinkle flour over the mushroom mixture and stir for 1–2 minutes. Gradually whisk in the milk and broth, bringing the mixture to a gentle simmer. Cook for 3–4 minutes until thickened to a gravy-like consistency.
5. Remove from heat and stir in cream cheese, Worcestershire sauce, onion powder, smoked paprika, salt, and pepper until smooth. Fold in the green beans.
6. Pour the filling into the prepared baking dish and spread evenly. Arrange tater tots in a single layer across the entire surface, covering the filling completely.
7. Bake uncovered for 30 minutes until the tater tots are golden and crisp and the sauce is bubbling at the edges.
8. Sprinkle cheddar cheese over the top and return to the oven for 8–10 minutes until the cheese is melted and beginning to brown.
9. Let rest 5 minutes before serving. Garnish with fresh chives.

Cook's Notes: For extra crunch, run the casserole under the broiler for 2–3 minutes after the cheese melts. This dish holds well in a warm oven (90°C / 200°F) for up to an hour, making it ideal for potlucks. Canned fried onions can be scattered over the cheese for a traditional nod to the classic 1950s recipe.
