Ingredients

Scale

Green Beans

  • 1 lb green beans (fresh or frozen)

Cream of Mushroom Soup

  • 1 can cream of mushroom soup

Milk

  • 0.5 cup milk (whole milk recommended)

Onion Topping

  • 1 cup fried onions (plus extra for topping)

Cheese (optional)

  • 1 cup shredded cheddar cheese (optional)

Garlic

  • 2 cloves garlic (minced)

Onion

  • 1 small onion (chopped)

Smoked Paprika (optional)

  • 1 teaspoon smoked paprika (optional, for flavor)

Seasoning

  • To taste black pepper

Instructions

  1. Prep and gather ingredients

    Preheat your oven to 180°C (350°F) and gather all your ingredients so everything is ready to go when you start cooking.

  2. Sauté aromatics

    In a large skillet, sauté chopped onion and minced garlic over medium heat until they turn translucent and fragrant, about 5 minutes.

  3. Blanch and sweeten beans

    Add the green beans to the skillet and cook for another 3-4 minutes, stirring occasionally, until they start to blister and smell sweet.

  4. Make the sauce

    In a mixing bowl, combine the cream of mushroom soup, milk, smoked paprika (if using), and a pinch of black pepper. Stir until smooth and well blended.

  5. Combine everything

    Add the cooked green beans, sautéed onions, and garlic to the bowl, then gently fold everything together to coat the beans evenly.

  6. Transfer to dish

    Transfer the mixture into a baking dish, spreading it out evenly with a spatula.

  7. Add toppings

    Sprinkle shredded cheese (if using) and a generous handful of crispy fried onions on top for added flavor and crunch.

  8. Bake

    Bake uncovered in the preheated oven for 20-25 minutes, until the casserole is bubbling around the edges and the top is golden brown.

  9. Rest and serve

    Remove from the oven and let it rest for 5 minutes, allowing the flavors to settle and the top to crisp up nicely. Garnish with extra fried onions if desired, then serve warm and enjoy the creamy, crunchy goodness.

Notes

  • Can be made dairy-free by using a plant-based milk and mushroom soup substitute.
  • For extra mushroom flavor, sauté a handful of mushrooms with the onions.
  • Leftovers refrigerate well for up to 3 days; reheat gently to avoid sogginess.
