Quality Seasonings

The Difference in Cooking with Lori Seasoning Packets

When I created my seasoning packets, I knew they had to be made with only the best ingredients. That’s why they contain no anti-caking agents, no MSG, and no preservatives—just pure seasonings and herbs. This is extremely important to me because I want every meal to be as clean and wholesome as possible. With my seasoning packets, you can enjoy bold flavors without the unnecessary additives found in store-bought mixes. Every blend including this Mexican Lentil Soup is crafted to bring out the best in your dishes, making home cooking easier, healthier, and more delicious.

Cooking Time for Lentil Varieties

Split red lentils – Cook the fastest (about 5-10 minutes) and create a creamy texture.

Brown lentils – Take 20-40 minutes to cook, hold their shape well, and have a mild earthy flavor.

Green lentils – Take about 45 minutes to cook, hold their shape, and have a slight peppery flavor.

Whole red lentils – Cook in 30 minutes and become slightly mushy.


FAQ

Do I need to soak lentils before cooking?

No, but rinsing them removes excess starch and debris.

Can I make the Lentil Soup in a slow cooker?

Yes! Cook on high for 4 hours if using split red lentils. If using brown or green lentils, add more cooking time.

This Mexican lentil soup recipe is quick, easy, and bursting with bold flavors. Whether you’re making it for a cozy dinner or meal-prepping for the week, it’s a satisfying dish that the whole family will love!
