17. Roasted Cauliflower and Corn Chowder

A creamy, hearty roasted cauliflower and corn chowder with pepper jack cheese for a subtle spicy heat — perfect comfort food for cold months that can be blended to any desired consistency.

14. Keto Zuppa Toscana

A wickedly good keto Zuppa Toscana — a low-carb Olive Garden copycat recipe with ground pork, radishes, and aromatic spices in a creamy broth — ready in under 30 minutes in an Instant Pot or on the stovetop. Using radishes as the potato substitute is the genius move that makes this genuinely keto without sacrificing any of the original's character — radishes soften beautifully in the broth and take on a potato-like texture and mildness that most guests genuinely cannot distinguish from the real thing.

Ingredients

• 1 lb ground Italian pork sausage (or ground pork + Italian seasoning)
• 1 bunch radishes, quartered (about 2 cups)

3. Reduce heat and simmer for 15 minutes until radishes are tender and have softened to a potato-like texture.

A hearty, authentically seasoned Japanese shio ramen with a clean salt-forward broth, menma, and braised pork — completed within 45 minutes with broth and menma components that can be prepared ahead for faster assembly. The salt-seasoned broth is the most clean, most refined of all ramen styles and produces a light, golden, deeply aromatic bowl that is naturally low-carb when served with shirataki noodles or spiralised zucchini instead of wheat noodles.

Ingredients

• 4 cups chicken broth (high quality — this is the star)

• 1 tablespoon mirin (or ½ teaspoon sugar-free sweetener)

1. Combine chicken broth, ginger, and garlic in a pot. Bring to a gentle simmer over medium heat for 10 minutes to infuse. Strain out the ginger and garlic.

3. Prepare shirataki noodles or spiralised zucchini according to package instructions. Divide between serving bowls.
4. Ladle the hot broth over the noodles. Top each bowl with sliced pork, a halved soft-boiled egg, scallions, nori, and menma. Serve immediately.

• 3 cloves garlic, minced
• 2 shallots, thinly sliced and fried until golden
• 2 tablespoons soy sauce or tamari
• 1 teaspoon white pepper + salt

A richly flavoured healthy mushroom soup with sautéed mushrooms, onions, and herbs in a deeply savoury broth — a genuinely wholesome, clean-eating weeknight answer that is naturally keto, naturally low in carbohydrates, and one of the most intensely flavoured soups available from the simplest ingredients.
