Instructions

1. In a skillet over medium heat, sauté onions and mushrooms until soft and golden.

2. Add minced garlic and flour, cooking 1 more minute until fragrant.

3. Slowly whisk in chicken broth and heavy cream; bring to a simmer and season with salt, pepper, and cayenne.

4. Place fresh green beans in the slow cooker and pour the mushroom cream sauce over them; stir gently.

5. Cover and cook on LOW for 5-6 hours.

6. About 10 minutes before serving, stir in half of the French-fried onions to soften slightly; reserve the other half for garnish.

7. Transfer to a serving dish and top with remaining fried onions before serving.

Notes

Cool casserole completely before storing in an airtight container in the refrigerator for up to 3 days.

Reheat individual portions in the microwave until hot; topping will lose some crunch.

Freeze for up to 2 months; thaw overnight in the fridge before reheating.

Do not use canned or frozen green beans for best texture.

For extra flavor, optional additions include shredded rotisserie chicken, sharp cheddar cheese, roasted garlic, or crumbled bacon.
