Sawmill gravy is a classic Southern staple, often served over biscuits, chicken-fried steak, or mashed potatoes. Traditionally made with a roux of fat and flour, this microwave version uses cornstarch for a smooth, lump-free consistency—no stove required! If you're looking for an easy white gravy recipe that comes together in minutes, this microwave method is the perfect solution.
In a microwave-safe bowl or measuring cup, whisk together the cold milk, cornstarch, salt, and pepper until smooth.
Microwave on high for 2 minutes, then stir well.
Continue microwaving in 30-second intervals, stirring after each, until the gravy reaches your desired thickness (usually 3–4 minutes total).
Let it sit for a minute to thicken further, then stir and serve over biscuits, toast, or your favorite dish.
Notes
Dairy-Free Option: Use unsweetened almond, oat, or coconut milk instead of regular milk.
Thicker Gravy: If the gravy is too thin, microwave in 15-second increments, stirring between each, until desired consistency is reached.
Smoother Texture: Whisk the mixture well before and after microwaving to prevent lumps.
Make It Sausage Gravy: Stir in crumbled cooked sausage after thickening for a heartier version.
Storage & Reheating: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in short microwave bursts, stirring frequently, and add a splash of milk if needed to thin it out.
Peppery Kick: Add extra black pepper for a classic Southern-style flavor.
Serving Suggestions: Perfect over biscuits, fried chicken, mashed potatoes, or breakfast casseroles.
