How to Make Philly Cheesesteak French Onion Soup

Step 1: Sauté the Onions

  • Heat 3 tablespoons of oil in your large Dutch oven or soup pot over medium heat.
  • Add the onions to the pan and sauté until soft, about 12 minutes.

Step 2: Caramelize the Onions

  • Add the butter to the pan with the onions.
  • Continue cooking until they start to brown, which takes about another 10 minutes.

Step 3: Flavorful Additions

  • Stir in Worcestershire sauce (or coconut aminos), garlic, thyme, bay leaves, salt, and pepper.
  • Cook this mixture for about 5 minutes to enhance flavors.

Step 4: Deglaze the Pan

  • Pour in the cooking apple juice to deglaze.
  • Use your rubber spatula to scrape up any bits stuck to the bottom of the pan.

Step 5: Simmering Broth

  • Add beef stock to your pot.
  • Bring it to a boil before reducing heat to low. Let it simmer for about 25 minutes.

Step 6: Prepare Peppers and Steak

  • In a separate large skillet over medium heat, add remaining tablespoon of olive oil.
  • Sauté the bell peppers seasoned with salt and pepper for about 5 minutes.
  • Incorporate steak into this skillet and cook until desired doneness is reached.
  • Add cooked peppers and steak back into your main soup pot. Taste and adjust salt if needed.

Step 7: Assemble Ramekins

  • Discard bay leaves from your soup mixture.
  • Divide soup among four large oven-proof ramekins.
  • Top each ramekin with two pieces of toasted bun and one slice of provolone cheese. Evenly distribute Gruyere cheese on top.

Step 8: Broil Until Bubbly

  • Preheat your oven’s broiler setting.
  • Place ramekins under broiler; cook until cheese is bubbly and golden brown.

Step 9: Final Touches

  • Garnish with fresh thyme sprigs and a sprinkle of black pepper right before serving.

Common Mistakes to Avoid

When making Philly Cheesesteak French Onion Soup, it’s easy to overlook some details. Here are common mistakes to watch for:

  • Skipping the Caramelization: Failing to properly caramelize the onions can lead to a lack of depth in flavor. Spend enough time cooking them until they are golden brown for the best taste.
  • Ignoring Seasoning Adjustments: Not tasting and adjusting seasoning throughout cooking can result in bland soup. Always taste as you go and add more salt or pepper if needed.
  • Using Low-Quality Ingredients: Low-quality broth or cheeses can ruin the dish. Use fresh, high-quality ingredients for a richer and more satisfying flavor.
  • Overcooking the Steak: Cooking the steak too long can make it tough. Add it at the right time and cook only until it reaches your preferred doneness.
  • Not Deglazing Properly: Skipping deglazing may mean missing out on delicious bits stuck to the pan. Scrape those bits up with your liquid to enhance flavors.
  • Forgetting About Garnishes: Neglecting to garnish your soup can make it look less appealing. Fresh herbs or a sprinkle of black pepper adds a nice touch.

Refrigerator Storage

  • Duration: Store leftover soup in an airtight container for up to 4 days.
  • Containers: Use glass or plastic containers that seal well.

Freezing Philly Cheesesteak French Onion Soup

  • Duration: Freeze in airtight containers for up to 3 months.
  • Containers: Ensure containers are freezer-safe and leave space for expansion.

  • Microwave: Heat in a microwave-safe bowl, stirring every minute until hot.
