Herb Cheese Croquettes with Lemon Caper Mayo

Crispy golden croquettes built on a foundation of fluffy mashed potatoes, ricotta, and sharp parmesan, with melted mozzarella pockets hidden inside. Fresh herbs--parsley, thyme, and rosemary--brighten the potato base, while lemon zest adds citrus notes. The panko crust delivers satisfying crunch that gives way to creamy centers. Serve these as an elegant appetizer at dinner parties, a substantial vegetarian main with salad, or impressive finger food for gatherings. This version avoids heavy cream, relying on ricotta for richness, making them feel indulgent yet restrained.

Tips
Grate warm potatoes for easier handling and better texture, which helps them bind without extra starch or egg.
Ensure oil reaches 350F before frying; use a thermometer to prevent undercooked centers or greasy exteriors.
Prepare croquettes up to frying 1 day ahead, stored breaded on a parchment-lined tray in the fridge, for convenience.
Good to Know
Refrigerate cooked croquettes in an airtight container up to 3 days. Reheat in a 350F oven for 5-7 minutes to restore crispness; do not microwave.
Form and bread croquettes up to 1 day ahead; freeze on a parchment-lined tray, then transfer to a freezer bag up to 2 months. Fry from frozen, adding 1-2 minutes to frying time. Prepare sauce up to 2 days ahead; store covered in the refrigerator.
Serve warm as a first course with lemon caper mayo, or as a main course with mixed greens and extra lemon wedges. Garnish with fresh parsley and thin lemon slices. Pairs well with crisp white wine or sparkling water.
Common Mistakes
Do not skip cooling potatoes to avoid mushy, oversodden croquettes.
Do not underfill or overfill mozzarella pockets; aim for a small piece to prevent leakage during frying.
Do not skip the egg wash step to avoid uneven breadcrumb adhesion.

FAQ
Can I bake these instead of frying?
Yes. Arrange breaded croquettes on a parchment-lined baking sheet, spray with cooking oil, and bake at 400F for 15-18 minutes, turning halfway. The texture will be less crispy but still pleasant.
What if my croquettes are leaking cheese?
Mozzarella pieces are too large or positioned too close to the surface. Use smaller cheese pieces, bury them deeper in the potato mixture, and ensure the croquette shell is at least half an inch thick on all sides.
How long can I keep croquettes before serving?
Cooked croquettes stay fresh in the refrigerator for 3 days in an airtight container. Breaded uncooked croquettes keep up to 1 day in the fridge or 2 months frozen. Reheat before serving.
