1. Onions

Select sweet onions like Vidalia or yellow onions for a rich, caramelized flavor. Slice them thinly for optimal texture.

2. Beef Broth

Choose a high-quality, low-carb beef broth or make your own to control the ingredients. Ensure it aligns with your keto preferences.

3. Butter and Olive Oil

A combination of butter and olive oil adds richness to the soup while enhancing the caramelization of the onions.

4. Garlic

Minced garlic brings a savory depth to the soup. Adjust the quantity based on your preference.

5. Thyme

Dried or fresh thyme leaves contribute earthy notes that complement the sweetness of the onions.

6. Bay Leaves

Add bay leaves for a subtle herbal aroma that enhances the overall flavor profile.

7. Salt and Pepper

Season the soup with salt and pepper to taste, adjusting as needed during the cooking process.

8. Beef Chuck or Brisket (Optional)

For added richness and heartiness, consider adding small pieces of beef chuck or brisket to the soup.

9. Gruyère or Swiss Cheese (Optional)

For a traditional touch, melt Gruyère or Swiss cheese on top of the soup when serving.


  1. Sauté Onions: Set the pressure cooker to the sauté function. Add butter and olive oil, then sauté sliced onions until they caramelize, stirring occasionally.
  2. Add Garlic and Thyme: Stir in minced garlic and thyme, continuing to sauté until fragrant.
  3. Deglaze with Beef Broth: Pour in the beef broth to deglaze the pot, scraping any flavorful bits from the bottom. Add bay leaves, salt, and pepper.
  4. Pressure Cook: Set the pressure cooker to cook on high pressure for about 10-15 minutes. If adding beef, ensure it’s cut into small, bite-sized pieces before adding.
  5. Release Pressure: Once the pressure cooking is complete, perform a quick pressure release or follow the manufacturer’s instructions for your specific pressure cooker.
  6. Serve Hot: Ladle the hot Keto Onion Soup into bowls. Optionally, melt Gruyère or Swiss cheese on top for added richness and traditional flair.
