To update recipe management after massive amounts of cooking, I recommend going digital with your recipes and to also keep a hard copy system. If you are visual like me, you will want to see the recipe you are preparing and you will also like having it scanned on your phone in the notes app or another app with more bells and whistles. This will give you the ability to share with family and friends and at a moment's notice you will have access to the ingredient quantities for shopping.
Thin out recipes and put into categories then place in paper file folders. Categories could be the following: Beverages, Appetizers, Breakfast/Brunch, Soups, Sauces/Marinades, Salad Dressings, Salads, Side Dishes, Pasta, Breads, Grains, Poultry, Beef, Lamb, Veal, Seafood, Asian/Thai, Indian, Mexican/Southwestern, Slow cooker/Instant Pot, Dinner parties/Menus, Holidays, Desserts, Repeaters (frequently prepared) Order 3 ring binders from Amazon such as the Meadowsweet Kitchens recipe binders and the protector pages for full sheets, for 3×5 and 4×6 size recipes (this will fit printed 8×11 recipes, newspaper clippings, magazine clippings, index cards, and handwritten recipes from someone special). Scan or delegate the scanning process to a friend or relative completing a few categories at a time so as not to become too overwhelmed. Put the paper copies in a 3 ring binder or binders divided into your categories with printed labels as you go (if using 3 binders you could fit 6-8 categories in each for quick reference). Bon Appétit!
