My grandmother always insisted on freshly grated cheese for au gratin dishes. Years of experience have proven her right - pre-shredded varieties simply don't create the same smooth, luxurious sauce.
Serving Suggestions
This au gratin pairs beautifully with roasted chicken, grilled steak, or holiday turkey. Serve alongside crusty bread to soak up the rich sauce, or complement with roasted potatoes for a hearty meal.
Recipe Variations
Consider adding crispy bacon bits, creating a herb-parmesan breadcrumb topping, incorporating wild mushrooms, or adding red pepper flakes for heat.
Storage Instructions
Keep leftovers in an airtight container up to three days. Reheat in the oven to maintain sauce consistency. For advance prep, assemble without final cheese topping and refrigerate up to 24 hours.
Tips for Success
Take time with the sauce preparation and allow proper time for browning in the oven for best results.
Texture Guidelines
Cook Brussels sprouts until just tender while maintaining their structure - this allows them to hold the sauce while keeping their shape.

Frequently Asked Questions
- → Can I get this ready beforehand?
- You can prep the sprouts and shred the cheese ahead, but it's better to combine and bake just before serving.
- → What happens if I don’t have all the cheese types?
- Although the three-cheese blend gives the best taste, you can use whatever melty cheeses are on hand.
- → Can frozen sprouts work here?
- Fresh sprouts are a better choice since frozen ones tend to get a bit soggy.
- → What kind of pan works best?
- A cast iron skillet or oven-safe pan is ideal, but you can always transfer everything to a baking dish instead.
- → Why would you add nutmeg?
- Just a tiny pinch of nutmeg brings out the creamy sauce’s flavor and adds a cozy note without being too noticeable.
