What is Keto Pasta e Fagioli Soup?

Keto pasta e fagioli soup is a low-carb adaptation of the traditional Italian dish known for its blend of pasta, beans, and robust flavors. Our version transforms this classic into a keto-friendly meal by replacing high-carb ingredients like high-protein and reduced-carb pasta and significantly reducing or eliminating beans. Instead, we incorporate nutrient-dense ingredients like ground beef, turkey sausage, and cauliflower rice to create a hearty low-carb stew.

This keto Italian soup uses a tomato-based keto broth made from sugar-free tomato sauce and diced tomatoes. Additional ingredients, such as garlic, onion, and Italian seasoning, enhance its flavor profile. For those seeking a dairy-free keto soup, toppings like Parmesan cheese can be omitted. By maintaining its comforting essence, this soup becomes a gluten-free, high-protein keto pasta option perfect for low-carb dieters looking for satisfying meals.

How did we make Keto Pasta e Fagioli Soup that’s lower in carbs?

We modified the traditional recipe to create a keto pasta fagioli that's flavorful and low in carbs. Replacing traditional pasta with Pete’s Pasta noodles reduces the carbohydrate content significantly. Meanwhile, zucchini noodles, or "zoodles," maintain texture and pair well with the tomato-based keto broth.

Instead of incorporating large amounts of beans, we added just a small portion of red beans for flavor while ensuring the dish remains a low-carb comfort food. For those seeking an even lower-carb option, eliminating beans entirely works well, substituting with nutrient-dense cauliflower rice for similar bulk and texture.

Ground beef and turkey sausage deliver protein and depth, transforming this into a high-protein keto soup. We seasoned the broth with Italian herbs, garlic, and onion for authentic flavor. Using low-sodium beef broth ensures a hearty low-carb stew that's keto-friendly and health-conscious.

For added richness, olive oil provides healthy fats essential for a keto diet. Zoodles soak up the savory broth while optional Parmesan cheese completes this gluten-free pasta fagioli. For a dairy-free keto soup, omitting the cheese keeps the dish compliant. This adaptation remains a satisfying, low-carb Italian classic perfect for keto dieters.

How to make this Pasta e Fagioli Soup even lower in carbs

Reducing the carb content in keto pasta fagioli focuses on adjusting ingredients without sacrificing flavor. To further lower carbs, omit beans entirely. Replace their texture and bulk with cauliflower rice, which works well in a tomato-based keto soup. For pasta alternatives, choose Pete’s Pasta noodles. Both options are excellent for creating a low-carb pasta soup with minimal carbohydrates.

Limit carrots or eliminate them completely if you're reducing natural sugars in this keto Italian soup. Instead, increase zucchini or celery as alternatives to maintain the balance of vegetables. Opt for sugar-free tomato products like crushed tomatoes or tomato paste to ensure the base remains a keto-friendly broth.

For protein, stick with a combination of ground beef and turkey sausage for a hearty low-carb stew. Using high-quality Italian sausage also boosts flavor without added carbs. Avoid dairy, such as Parmesan cheese, in favor of a dairy-free keto soup if needed, or keep it minimal for a gluten-free pasta fagioli that aligns with keto dietary patterns.

What makes this soup extra flavorful?

The distinct seasoning and ingredient pairing elevate this keto pasta fagioli into a standout low-carb comfort food. Ground fennel enhances the savory depth, while red pepper flakes provide a subtle kick. Adding a Parmesan rind during cooking infuses richness into the keto-friendly broth, yielding a more robust, cheesy undertone. These choices enhance the base of this keto Italian soup without adding unnecessary carbs.

Using sugar-free tomato sauce and diced tomatoes ensures the soup remains a tomato-based keto soup while delivering authentic Italian flavors. Incorporating olive oil adds healthy fats, while garlic, onion, and Italian herbs bring aromatic layers to the dish. For texture, swapping traditional beans with cauliflower rice or limiting them provides a lower-carb alternative, maintaining balance in this satiating hearty low-carb stew.

For protein, the combination of ground beef and Italian turkey sausage creates a satisfying high-protein keto soup. Optional garnishes like fresh parsley and grated Parmesan cheese add freshness and enhance presentation, making this low-carb pasta soup both flavorful and appealing.

Crafting keto pasta fagioli begins with selecting low-carb ingredients. We replace traditional pasta with protein-rich pasta noodles to minimize carbs while maintaining a satisfying texture. Ground beef and Italian turkey sausage form the protein-rich base, creating a hearty low-carb stew perfect for keto dieters.
