Allrecipes Low-Carb Yellow Squash Casserole Swaps Almonds for Crackers

When yellow squash starts stacking up on the counter, this casserole gives keto cooks a real way to use it before it goes soft. The recipe, submitted by Tigray and updated on April 9, 2026, was built to use up a large amount of squash, and it keeps that practical goal front and center while still delivering the kind of baked side dish that feels at home at any table.

The dish has earned 4.7 stars from 230 ratings, along with 170 written reviews and 49 photos. It makes 8 servings and comes together in about 55 minutes, with 20 minutes of prep and 35 minutes of cooking. That timeline matters for anyone trying to turn a surplus vegetable into dinner without a long project in the kitchen.

The low-carb angle comes from a few clear swaps that make the recipe work for keto without losing the comfort-food feel. Instead of crackers, it uses almonds. Instead of milk, it uses whole cream. The ingredient list stays focused: olive oil, butter, onion, garlic, yellow squash, salt, pepper, chopped raw almonds, shredded Colby-Monterey Jack cheese, heavy whipping cream, eggs, and roasted salted almonds for the top. The result leans rich and savory, with the cheese and cream giving the casserole its body while the almonds add structure.

The method builds that texture step by step. Onion and garlic soften in oil and butter first, then the squash cooks just enough to start losing its raw edge. From there, the almonds, cheese, cream, and eggs are mixed in and baked until the top layer turns browned and crunchy. That finish is one of the recipe’s strongest selling points because it replaces the usual cracker crust with something that still feels substantial, but keeps the carb count in check.

The recipe also fits the way squash casseroles already travel through home kitchens. Allrecipes’ classic yellow squash casserole uses a buttery cracker-and-cheese topping, and other squash casseroles from the site have relied on crackers, bread crumbs, or stuffing mix. This version keeps the familiar format while making it work for keto, and it still suits the settings where these dishes matter most: family gatherings, potlucks, and holidays. Zucchini can also stand in for the squash, or be mixed in with it, which makes the casserole even easier to use up whatever is on hand.
