Troubleshooting

Stuffing is too dry after baking.

Drizzle with extra warm broth, cover with foil, and return to oven for 10 minutes.

Sweet potato casserole is runny.

Let it rest 10-15 minutes after baking to firm up; ensure egg is added after sweet potatoes have cooled.

Cranberry sauce is too thick.

Stir in a little orange juice or water to loosen before serving.

Mashed potatoes are gluey.

Use a masher, not a mixer, and avoid overworking the potatoes.

Green bean casserole topping burns.

Add topping halfway through baking and cover with foil if browning too quickly.

Brussels sprout salad is soggy.

Dress just before serving and store sprouts separately from vinaigrette.

  • Brussels sprouts can be sliced and stored in Ziploc bags up to 3 days ahead.
