How to Make Italian Penicillin Soup
Step 1: Cook Vegetables
Start by adding your olive oil to a large pot over medium heat. Once warm, toss in your chopped carrots, onion, garlic, and celery along with salt and black pepper. Sauté these veggies for about 4-5 minutes until they’re slightly browned. This step helps bring out their natural sweetness and depth of flavor. If you’re short on time, don’t worry! You can skip this step by adding everything directly into the broth later.
Step 2: Simmer Soup
Next, pour in your broth (chicken or vegetable works perfectly!) along with the optional parmesan rind. Cover it up and turn up the heat until you reach a gentle boil. Then reduce the heat to medium-low and let it simmer for about 25-30 minutes until those lovely vegetables are very soft. Stir occasionally to keep everything mixed together nicely!
Step 3: Puree Vegetables
After simmering, carefully remove the parmesan rind. Now comes the fun part! Use an immersion blender to puree those veggies until they’re completely smooth. If you don’t have an immersion blender handy, simply transfer everything into a regular blender in batches—just be cautious since it’s hot! Once blended, return it to the pot.
Step 4: Cook Pasta
Time to add your pastina! Stir it into your beautiful soup and let it cook for another 8-10 minutes until it’s al dente. Remember to stir occasionally so it doesn’t stick together. If you’re planning on saving some leftovers, I recommend cooking the pasta separately to keep its texture intact.
Step 5: Add Lemon
Now for that burst of flavor! Squeeze in the juice from your lemon—this will brighten up all those delicious flavors. Give it a taste test and adjust seasonings as needed; add more lemon juice if you’re feeling zesty!
Step 6: Serve
Finally, ladle that lovely soup into serving bowls. Top each bowl with freshly grated parmesan, a sprinkle of black pepper, and maybe a drizzle of olive oil if you’re feeling fancy! Garnish with chopped parsley if desired. Now sit back and enjoy every comforting spoonful!
Pro Tips for Making Italian Penicillin Soup
Making Italian Penicillin Soup is all about enhancing flavors and ensuring the best texture. Here are some tips to make your soup irresistibly good!
- Use fresh vegetables: Fresh, high-quality veggies not only enhance the flavor but also provide better nutrition and vibrant colors, making your soup visually appealing.
- Adjust seasoning gradually: Start with a little salt and pepper, then taste as you go. This allows you to control the flavor and avoid over-seasoning, resulting in a perfectly balanced soup.
- Incorporate herbs: Adding fresh herbs like basil or thyme just before serving can brighten up the dish. Herbs bring freshness and depth that complements the hearty ingredients.
- Store pasta separately: If you’re planning to save leftovers, cook the pastina separately. This prevents it from becoming mushy when reheated, ensuring each bowl remains deliciously al dente.
- Experiment with lemon: The acidity of lemon juice can be adjusted based on your preference. Start with one full lemon, then add more if you like a tangy kick that elevates the overall flavor profile of the soup.
How to Serve Italian Penicillin Soup

- Mixed green salad: A light salad with greens like arugula or spinach tossed in a simple vinaigrette offers a refreshing contrast to the warmth of the soup.
