  • 1/2 teaspoon Dijon mustard

Tips & Substitutions

For a richer flavor, consider adding grated cheese like cheddar or Parmesan to the mixture. Greek yogurt can substitute for sour cream for a healthier option.

This dish pairs wonderfully with Sparkling Cranberry Muffins for a festive touch.

Frequently Asked Questions

Can I use fresh Brussels sprouts instead of frozen?

Absolutely! Just blanch fresh Brussels sprouts in boiling water for about 3-5 minutes before adding them to the casserole. This ensures they cook evenly and maintain their vibrant color and texture in the dish.

How can I make this recipe dairy-free?

To make the casserole dairy-free, use a plant-based yogurt or sour cream alternative, and substitute the butter with vegan margarine. Nutritional yeast can add a cheesy flavor without dairy, making it perfect for vegetarian recipes.

Can I prepare this dish in advance?

Yes, you can prepare the casserole ahead of time. Assemble the dish and cover it tightly with plastic wrap or aluminum foil. Store it in the refrigerator for up to 24 hours. When ready to bake, remove the cover and add a few extra minutes to the cooking time.
