Why You'll Love Green Bean Casserole

Tips and Tricks

• Don't over-brown shallots or they'll taste bitter. Remove when golden.
• Use the reserved shallot oil to boost mushroom flavor in the sauce.

Variations

• Swap chicken stock for vegetable stock to make vegetarian.
• Add fresh thyme or rosemary to mushroom sauce for an herby note.

• Garlic mashed potatoes
• Crispy roasted Brussels sprouts

Make Fried Shallots

Prepare Mushroom Sauce

1. Smash mushrooms under a pan, then chop roughly.
2. Heat 2 tablespoon reserved shallot oil and butter in a 12-inch nonstick skillet over high heat.
3. Add mushrooms and cook, stirring, until liquid evaporates (~7-10 min).
4. Add garlic; cook 30 seconds until fragrant.
5. Stir in flour; cook 1-2 minutes until light golden.
6. Whisk in soy sauce, lemon juice, chicken stock, and cream.
7. Simmer until thickened (~5 min). Season with salt and pepper.

Notes

Storage: The casserole itself keeps well, cover and refrigerate for up to 3 days, then reheat covered in a 350°F oven until warmed through. The fried shallots on top will soften once stored, so if you're making this ahead, hold back a portion of the shallots and add them fresh right before serving.
