  • Yield: 6 servings

Ingredients

  • 1 lb fresh green beans, trimmed
  • 1 tbsp olive oil
  • 1 cup fresh mushrooms, sliced
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 1 cup low-fat milk
  • 2 tbsp whole wheat flour
  • 1/2 cup reduced-fat sour cream
  • 1/2 cup low-sodium vegetable broth
  • 1/4 cup grated Parmesan cheese
  • 1/3 cup whole wheat breadcrumbs
  • Salt, to taste

  • 1/4 tsp paprika
  • Olive oil spray

Instructions

  1. Preheat oven to 375°F and lightly grease a baking dish with olive oil spray.
  2. Blanch green beans in boiling salted water for 4 minutes. Transfer to ice water, then drain and set aside.
  3. Heat olive oil in a skillet over medium heat. Sauté onion until translucent.
  4. Add mushrooms and cook until golden brown. Stir in garlic and cook 1 more minute.
  5. Sprinkle flour over the mushroom mixture, stirring to coat. Slowly pour in milk and broth while stirring to avoid lumps.
  6. Simmer sauce until thickened. Remove from heat and stir in sour cream, salt, pepper, and paprika.
  7. Mix green beans into the sauce until evenly coated.
  8. Transfer mixture to prepared baking dish. Top with Parmesan cheese and breadcrumbs.
  9. Spray the top lightly with olive oil spray and bake for 20–25 minutes, until golden and bubbly.
  10. Let rest for 5 minutes before serving.

Notes

  • Use Greek yogurt instead of sour cream for added protein.
  • Substitute milk with coconut milk for a dairy-free version.
  • Replace Parmesan with nutritional yeast for a vegan option.
  • Top with chopped almonds or pecans for extra crunch.
  • Reheat in the oven to maintain crispiness.
