The Complete Shopping Rundown
- Salted butter, just 2 tablespoons to melt that onion and garlic in rich fat.
- One small white onion, minced fine so it blends better in the soup.
- Two heads of garlic - that's 24 cloves halved, giving you bold flavor.
- Fresh thyme sprigs, stems tossed, just the leaves to tease out fragrance.
- Half a teaspoon dried sage, adds that earthy scoop to the mix.
- Eight cups of chicken broth, make sure it's good quality for broth depth.
- Two tablespoons cornstarch for thickening, giving the soup perfect body.
- Parmesan cheese finely grated with the rind included for slow flavor release.
- Three large eggs, beaten ready for streaming into the hot soup.
- Half a baguette sliced diagonally for crostinis and extra Parmesan for topping.
Walking Through Every Single Move
Step one you gotta hit the oven preheated to 375°F, get it ready for those crostinis.
Step two, in your big pot over medium heat, melt butter slowly. Toss in that minced onion then cook it until translucent and soft, around five minutes.

Step three, add halved garlic cloves with fresh thyme leaves and sage. Cook 'em a good 4-5 minutes till garlic smells sweet and deep but not browned.
Step four, pour in broth plus the Parmesan rind. Get it boiling and then simmer uncovered for twenty minutes or so.
Next step, fish out that rind and use your immersion blender to puree smooth. If you don't got one, you can do it in batches in a blender but careful it's hot.
Step six, mix cornstarch with some hot soup making a slurry. Pour it back in the pot stirring well. Then beat those eggs, slowly drizzle 'em in stirring soup in circles so you get those silky ribbons. Season with salt and pepper, keep warm on low.
Last, line up the baguette slices on a tray. Sprinkle Parmesan on top. Bake for 8 to 10 minutes until crispy golden. Ladle your soup into bowls and dunk or float those cheesy crostinis on top.
Valve Hacks You Need to Know
- If you want it done fast, release pressure naturally for 10 minutes, then quick release to avoid overcooking.
- Check your float valve before cooking to make sure it moves freely, a stuck valve means no pressure build.
- Keep a spare sealing ring handy since it wears out, and swapping it out helps keep your cooker working smooth.
Your First Taste After the Wait
When you finally spoon that soup, you notice that bold garlicky punch right up front, but smooth and mellow thanks to the pureed broth.
The ribbons from the egg give a silky feel that just makes every bite kinda luxurious, without being heavy.
The cheesy crostinis add this crunchy, salty burst that plays so nice with the creamy soup underneath.
It's dang satisfying, the way flavors mingle and warm you from the inside out. Perfect for a chilly night or whenever your soul needs a pick-me-up.
Keeping Leftovers Fresh and Ready
- Store soup in an airtight container in the fridge, it'll last you 3 to 4 days easy.
- For the crostinis, keep them separate in a ziplock or paper bag so they stay crispy.
- If you wanna freeze soup, cool completely and portion in freezer-safe containers. Thaw overnight in fridge before reheating.
- When reheating soup, do it gently on low heat stirring often so those egg ribbons stay smooth and don't scramble.
Everything Else You Wondered About
- Can I use vegetable broth instead? Yeah, it works but the soup won't have that same depth and richness that chicken broth gives.
- What if I don't have an immersion blender? Use a regular blender but blend in batches and be super careful with hot liquid.
- Can I skip the cornstarch? It helps thicken and gives a silky texture, but if you skip it soup will be thinner, still tasty though.
- How important is the natural release? It keeps the soup texture nice and avoids splattering when you open the cooker.
- Can I use different cheeses on crostinis? For sure, mix it up with gruyere or mozzarella to change up flavor and meltiness.
- What if I only have pre-minced garlic? Using whole garlic halves is key here, pre-minced tends to cook differently and can burn easier.
