NOTES
1. Can I use frozen salmon for this recipe? Yes, just thaw it first. Since frozen fillets are usually smaller, make individual rolls instead of one large roll.2. Can I prepare this ahead of time? Yes. Assemble in the morning, cover, and refrigerate until ready to bake.3. What can I substitute for celery? Leek is a great option that gives a mild, sweet taste that pairs well with spinach.4. Variations
Swap Greek yogurt for sour cream for more richness.
Add chopped dill or parsley to the filling for an herby touch.
Replace spinach with Swiss chard or kale if that’s what you have.
5. Storage
Eat immediately: Best enjoyed fresh out of the oven.
Refrigerator: Store leftovers covered in foil for up to 1 day. Use them in an omelet filling the next morning.
Freezer: Not suitable for freezing due to the creamy filling.
