Heat a good glug of olive oil in a large pot or Dutch oven over medium heat. Toss in your finely chopped yellow onion and let it soften, stirring occasionally, until it's translucent and smells sweet, about 5-7 minutes. This is where the magic starts, creating a fragrant base for our High-Protein Broccoli Cheddar Soup. Don't rush it, or your soup will miss that deep, mellow onion flavor.

Add your minced garlic to the pot and cook for just about a minute until it's fragrant – you don't want it to burn, trust me, I've done that and it makes everything bitter! Pour in the chicken or vegetable broth and bring it to a gentle simmer. This step fills your kitchen with such a comforting aroma, it's honestly the best part of a chilly evening.

Add your fresh broccoli florets to the simmering broth. Let them cook until they're tender-crisp, maybe 5-8 minutes. We're not aiming for mush here! You want them bright green and still holding a little shape. This is the stage where I sometimes get distracted and overcook them, so keep an eye on those beauties! This ensures the broccoli in our High-Protein Broccoli Cheddar Soup retains its texture.

In a separate bowl, whisk together the whole milk and heavy cream. Gradually add this mixture to the pot, stirring constantly. Bring it back to a gentle simmer, but don't let it boil vigorously; we don't want anything scorching on the bottom. This is where the soup starts to transform, becoming wonderfully rich and preparing for its cheesy destiny.

Reduce the heat to low. Stir in the freshly grated sharp cheddar cheese a handful at a time, letting each batch melt before adding more. Add the cream cheese, nutritional yeast, and mustard powder. Continue stirring until everything is smooth and gloriously cheesy. This is the critical step for a truly High-Protein Broccoli Cheddar Soup!

Remove the pot from the heat. Now, here's my secret for that extra protein punch: stir in the Greek yogurt until it's fully incorporated and the soup is beautifully creamy. Season with salt, pepper, and a tiny pinch of nutmeg to taste. The soup should be thick, vibrant, and incredibly aromatic. Ladle it into bowls and get ready for a truly satisfying meal.
