In a high-speed blender or food processor, combine the cottage cheese, shredded cheese, and taco seasoning. Blend until the mixture becomes completely smooth and creamy. If needed, scrape down the sides to ensure everything is well incorporated.
Transfer the cottage cheese mixture to a microwave-safe bowl and sprinkle a little extra shredded cheese on top. Microwave for 1-2 minutes, stirring halfway through, until the cheese is fully melted and the dip is hot.
Give the queso dip a good stir to evenly combine the melted cheese. Then, top with chopped green onions, red bell peppers, or fresh cilantro for extra flavor. Pair this creamy, high-protein queso with tortilla chips, fresh veggies, or drizzle it over your favorite tacos and nachos. It’s best enjoyed warm, so dig in right away!
