For the Broth
• Chicken Broth – The light base of the soup; low-sodium chicken broth is recommended for better salt control.

• Celery Stalk – Offers earthiness and aroma; slice thinly (about ¼ inch thick) for optimal infusion.
• Carrot – Adds natural sweetness and important nutrients; cut into similar-sized pieces for even cooking.
• Fresh Mushrooms – Introduce umami and texture; opt for button or cremini mushrooms and slice them thinly to prevent overcooking.
• Green Onions – Great for garnish, adding a fresh crunch; chopped scallions work as a perfect substitute.

For Seasoning

Step‑by‑Step Instructions for Onion Soup

Step 1: Gather Ingredients and Tools
Begin by collecting all your ingredients and equipment for the savory onion soup. You’ll need chicken broth, beef broth, a medium onion, celery stalk, carrot, fresh mushrooms, green onions, and soy sauce. Prepare your large pot, slotted spoon, and fine mesh strainer. Setting up everything will streamline the cooking process, ensuring you have all you need at your fingertips.

Step 2: Prepare the Vegetables
Thinly slice the onion, celery, and carrot, aiming for uniform pieces as this helps with even cooking. Set the mushrooms aside; they’ll be added later to the broth. As you slice, enjoy the fragrant aroma that fills your kitchen. Proper vegetable preparation is crucial for enhancing the flavors that will shine through in your delicious onion soup.

Step 3: Combine Broths and Vegetables
In your large pot, combine the chicken and beef broths. Use a 4:2 ratio, which balances the light and rich flavors beautifully. Next, toss in the sliced onion, celery, and carrot. This mixture will create the flavor base for your onion soup. Heat over medium-high until it begins to boil, stirring occasionally to avoid sticking, and watch for steam rising.

Step 4: Bring to a Boil
Monitor the broth as it reaches a vigorous boil. This usually takes about 5-7 minutes. Be careful to prevent overflow by reducing the heat slightly if necessary. The bubbling broth will begin to release the sweet aromas of the cooked vegetables, indicating that your savory onion soup is on the right track.

Step 5: Simmer for Flavor Development
Once boiling, reduce the heat to low-medium and allow the broth to gently simmer for 25-30 minutes. The vegetables should become tender, and the flavors will meld beautifully as they release their natural essences. Look for the carrots to soften and the onions to turn translucent while maintaining their integrity in your comforting onion soup.

Step 6: Strain the Soup
After simmering, carefully strain out the cooked vegetables using a slotted spoon and a fine mesh strainer. This step ensures your broth is clear and showcases the rich flavors developed during cooking. The aromatic base will be the star of your onion soup, providing a clean canvas for the next ingredients to shine.

Step 7: Adjust Seasonings
Take a moment to taste the broth and adjust its flavor profile. Gradually add soy sauce, salt, and pepper to suit your liking, keeping in mind that the broth should preserve a delicate balance. Enhancing with seasonings at this stage is crucial to developing the overall savory depth of your onion soup.

Step 8: Add Mushrooms and Finish Cooking
Finally, incorporate the fresh mushrooms into the broth and let them cook for 2-3 minutes on low heat. This brief cooking time ensures they stay tender without becoming mushy. As they absorb the savory flavors, your onion soup will be on its way to perfection, highlighting both texture and rich umami notes.

Expert Tips for Onion Soup

Broth Control: Use low-sodium broths to manage saltiness effectively; this way, you can enhance the flavor without overwhelming it.
Slice Evenly: Aim for thin and even vegetable slices to ensure each piece cooks uniformly, releasing optimal flavors into the onion soup.
Watch the Heat: Avoid boiling too vigorously; a gentle simmer prevents cloudiness in your broth and maintains clarity.
Season Later: Add seasonings post-straining for best results; this allows you to adjust flavors without over-salting during cooking.
Mushroom Timing: Add mushrooms only in the last minutes of cooking to preserve their texture, preventing them from becoming mushy.

Make Ahead Options

These Benihana onion soup preparations are perfect for busy weeknights and can save you precious time!

The broth can be made ahead and stored for up to 3 days in the fridge, ensuring your soup has that robust flavor right when you need it. To finish the soup, simply heat the broth, add the fresh mushrooms, and allow them to simmer for 2-3 minutes before serving. This prep strategy means you can enjoy delicious, restaurant-quality onion soup at home without the stress!

How to Store and Freeze Onion Soup

Freezer: Portion the onion soup into freezer-safe containers or bags, ensuring they’re labeled. It can be frozen for up to 2-3 months without losing its rich flavors.

Reheating: When ready to enjoy, thaw overnight in the fridge if frozen. Reheat on the stovetop over low heat, stirring occasionally until hot, or in the microwave in short intervals.

Airtight Storage: Always use airtight containers for short and long-term storage to prevent freezer burn and retain the savory goodness of your homemade onion soup.

Benihana Onion Soup Recipe FAQs

How should I select ripe vegetables for my onion soup?
Absolutely! Look for vegetables that are firm and have vibrant colors. For onions, choose ones that are free of dark spots or soft places, indicating they’re fresh. Celery should be crisp and bright green, while carrots should be smooth and orange. Fresh mushrooms like button or cremini should have a firm texture and no signs of sliminess.

How should I store leftover onion soup?
Very easily! Once completely cooled, store the onion soup in airtight containers in the refrigerator for up to 3-4 days. Make sure to let it cool at room temperature before sealing it up, as this helps retain the best flavors. Alternatively, if you're craving some for later, you can freeze it for 2-3 months!

Can I freeze onion soup for later use?
Yes, you can! To freeze your onion soup, portion it into freezer-safe containers or resealable bags. Be sure to leave some space at the top for expansion, and label them with the date. When you're ready to enjoy it, thaw overnight in the refrigerator and reheat on the stovetop or in the microwave. This technique keeps the flavors intact beautifully!

What common mistakes should I watch for when making onion soup?
One pitfall to avoid is over-salting early in the cooking process. This can lead to an overly salty broth. Instead, season after straining to best control the saltiness. Also, remember to simmer gently rather than boiling vigorously; a gentle simmer keeps the broth clear and avoids cloudiness. If you're worried about mushy mushrooms, add them at the very end of cooking to maintain their delightful texture!

Are there any dietary considerations I should keep in mind?
Absolutely! If you have food allergies, be cautious with soy sauce, as it contains gluten. You can easily substitute with gluten-free soy sauce or tamari if needed. For a vegetarian version, use vegetable broth instead of chicken and beef broths. You can also enhance the umami flavor with extra soy sauce or mushrooms. Always feel free to customize the recipe to your dietary needs!
