Keto substitute for rice
For a rice-shaped side dish, use a prepared vegetable or shirataki product. These replace rice on the plate, not in recipes that rely on rice starch or absorption. Cook off excess moisture before adding sauce.
Cauliflower rice: 1 cup prepared for 1 cup cooked rice. Sauté until steam has escaped. It works in bowls and fried-rice-style lunches but will not absorb liquid like dry rice.
Broccoli rice: 1 cup prepared for 1 cup cooked rice. Pulse broccoli finely and sauté briefly. The flavor is stronger than cauliflower, so pair it with sauces or herbs.
Shirataki rice: 1 cup prepared for 1 cup cooked rice. Rinse and dry-fry as directed on the package. Check the label for added starches and allergens before treating a product as keto-friendly.

Keto substitute for potatoes
Choose a different vegetable for the job the potato was doing. No single alternative copies a potato’s starch, browning, and texture in every dish. These are serving swaps, not one-to-one replacements for potato flour or starch.
Cauliflower mash: 1 cup mash for 1 cup mashed potatoes. Steam and drain cauliflower very well before blending. Add olive oil to taste; it will be softer than potato mash.
Roasted turnips: 1 cup cooked for 1 cup roast potatoes. Cut into small cubes and roast until browned. Turnips have a mild bite and a softer interior than potatoes.
Roasted radishes: 1 cup cooked for 1 cup roast potatoes. Halve or quarter and roast until tender. Their peppery raw flavor mellows, though they do not become fluffy like potatoes.

Low-carb substitute for cornstarch
For a low-carb sauce, thicken gradually rather than replacing a tablespoon of cornstarch with a tablespoon of gum. The best option depends on whether the original starch thickened a sauce, set a filling, or made a crisp coating.
Xanthan gum: Start with a small pinch, not a 1:1 swap. Blend into a sauce a little at a time and wait for it to thicken. Too much can make the texture gummy; it does not replace cornstarch in a crisp coating.
Reduce the sauce: Simmer uncovered until thick enough. Use evaporation when the sauce can tolerate longer cooking. This adds no thickener, but it concentrates salt and flavors, so taste at the end.

Practical limits
Almond and coconut flours need recipe-specific methods rather than a universal one-to-one swap. Vegetable rice, mash, and noodles replace a serving, not the starch behavior of the original ingredient. Check packaged low-carb products for carbohydrates and allergens.
