- For extra creaminess, add a few tablespoons of heavy cream before baking.
- For a crispier finish, bake uncovered during the last 20 minutes.
- Fresh herbs provide the best flavor, but dried herbs work well too.

Storage

Q&A
Q: Can I prepare this ahead of time?
A: Yes. Assemble the casserole up to 24 hours in advance, cover, refrigerate, and bake when ready. Add the feta and walnuts during the final uncovered bake.
Q: Do I need to cook the beets first?
A: No. Thinly sliced raw beets become tender during baking.
Q: Can I use different vegetables?
A: Yes. Carrots, parsnips, butternut squash, turnips, rutabaga, and celeriac all work well. Slice them to a similar thickness for even cooking.
Q: Why cover the dish with foil first?
A: Covering traps steam, helping the dense root vegetables soften before the final uncovered bake browns the top.
Q: Can I omit the feta?
A: Yes. The bake is still flavorful without it, or you can substitute goat cheese, ricotta salata, or a dairy-free feta alternative.
Q: Can I toast the walnuts first?
A: Yes. Toasting them for 5–8 minutes at 350°F (175°C) enhances their flavor and crunch.
Q: Is this gluten-free?
A: Yes, as written, provided all packaged ingredients (such as feta and seasonings) are certified gluten-free if needed.
Q: What pairs well with this dish?
A: It complements roasted chicken, grilled steak, baked salmon, pork tenderloin, lentil loaf, or a simple green salad for a complete meal.
