Soups and stews use traditional high-carb thickeners such as flour, cornstarch, arrowroot powder, or potato starch. But, those on a keto diet might find these high-carb options challenging.

One main principle of the ketogenic diet is limiting carb intake to trigger ketosis, where the body uses fat for energy. Common thickeners like flour and cornstarch can add extra carbs to your meals, hindering this goal. As cooks on a low-carb diet aim to make tasty soups while sticking to keto rules, they seek keto thickener alternatives to high-carb thickeners.

Luckily, in keto cooking, you have many thickening agent substitutes to thicken without straying from your low-carb goals.

If you like using dairy in your cooking, heavy cream is a great keto thickener for a creamy texture. Heavy whipping cream adds flavor and creaminess to sauces but doesn’t thicken them. Simmer the cream to reduce water content and make your dish thicker.

You can choose cream cheese or sour cream to make a dish creamier. Adding a bit of butter to your sauce or soup can also help create a creamy texture without being overly thick. Butter has natural emulsifiers and a high fat content that helps stabilize and bind ingredients. For a dairy-free alternative, try coconut cream in creamy sauces.

Egg Yolks

Eggs are an excellent keto thickener option. They are low in net carbs and rich in fat and protein. When thickening with eggs, avoid adding yolks to hot foods directly to prevent scrambling. Remember to temper the egg yolks before using them as a thickener.

To avoid curdling your eggs, whisk the egg yolks in a separate bowl. Gradually mix some hot liquid with the yolks, whisking constantly to warm the mixture. Once combined, add the tempered eggs to the main sauce while stirring gently. Don’t let the liquid boil, as it will result in scrambled eggs.

Keto Thickener FAQs

How do I adjust the thickness of a soup if I’ve added too much thickener?

If your soup is too thick, fixing it is easy. To thin it out, slowly add small amounts of liquid like broth or water, stirring until it’s just right. This method lets you adjust the soup without losing flavor. Also, consider tweaking the seasonings to balance the taste. With some careful adjustments, you’ll save your soup and get the perfect texture for a delicious meal.

Can I use dairy-based thickeners like heavy cream and cheese in keto recipes?

While heavy cream and cheese are excellent dairy-based keto-friendly thickeners in traditional recipes, they might pose challenges in dairy-free alternatives. However, there are viable substitutes that maintain a dairy-free and keto-friendly profile. For thickening soups, coconut cream or nut-based alternatives like almond or cashew butter can replicate the richness of heavy cream.
