All the Pieces for This Meal
For making that classic Walkabout Onion Soup, you gotta gather some key ingredients first. You'll want 2 cups of yellow sweet onions, thinly sliced. These give you that mellow onion sweetness that tastes best when they're softly sautéed.
Butter is your buddy here. Two tablespoons do the trick to melt everything together. Then you bring in a whole 15-ounce can of chicken broth plus a couple chicken bouillon cubes to deepen the flavor even more. It's the broth depth thing again-you gotta have it rich.
Don't forget a pinch of salt and some fresh ground pepper, about a quarter teaspoon each, to balance out the sweetness. Velveeta cheese is next, about a quarter cup, cubed and squeezed to fit your measuring cup. It melts down all creamy and smooth into the soup.
Then, the white sauce. You'll need 1 ½ to 1 ¾ cups of that creamy beauty. For the white sauce you melt 3 tablespoons butter, stir in 3 tablespoons flour, then slowly whisk in 1 ½ cups whole milk adding a quarter teaspoon salt. It's simple but makes the soup extra velvety. Top it all with shredded cheddar cheese for garnish - that sharp cheddar adds a nice punch when melted on top.
How It All Comes Together Step by Step
First, you wanna melt two tablespoons of butter in a large saucepan over medium heat. Keep an eye on it so it doesn't brown. Add your thinly sliced yellow onions and sauté 'em until they're soft and translucent - takes about 10 minutes. You'll see them shimmer and smell sweet.
Next, pour in your 15-ounce can of chicken broth. Toss in the salt, fresh ground pepper, and those two chicken bouillon cubes. Stir it all around so the cubes dissolve and bring the mixture up to a gentle simmer.

Now time for the Velveeta cheese cubes. Stir these in until they're totally melted and blended in, giving the soup a creamy texture that's just right. Once that's done, gently stir in the prepared white sauce. Keep warm but don't let it boil, you gotta protect that silky smoothness.
Meanwhile, set up your pressure cooker. Pour the soup mixture in and seal the lid with that sealing ring snugly in place. Let the cooker build pressure and wait for the valve hiss - that means it's cooking at full power. Let it cook at high pressure for about 10 minutes.
When time's up, let it go through natural release so the pressure drops slowly. This keeps your soup creamy without splatter. Open the lid carefully once the pressure is fully released and ladle the soup into bowls.
Finish by sprinkling shredded cheddar cheese on top of each bowl. It melts right in from the heat and you get that perfect cheesy crust on your walkabout onion soup. Serve it up and watch your family dig in!
Smart Shortcuts for Busy Days
You won't always have time to make a homemade white sauce so here's a trick. Use a good quality jarred alfredo or white sauce instead. It's not exactly the same but close enough to keep that creamy vibe going.
If you're really pressed for time, frozen pre-sliced onions work fine too. Just toss 'em in a bit longer at the sauté stage so they soften up good.
Buy pre-shredded cheddar cheese so you don't gotta fiddle with grating. Saves you at least a minute or two which counts.
Using low sodium chicken broth lets you control the salt easier without worrying about over-salting when you add bouillon cubes.
Lastly, toss all your dry ingredients and seasoning in a small container ahead of time. It's kinda like your soup seasoning kit ready to go whenever you wanna cook.
The Flavor Experience Waiting for You
When you taste this soup, the first thing you feel is that sweet onion flavor softened by buttery richness. It's kinda like warm hugs in a bowl.
The creamy Velveeta and white sauce team up to coat your tongue with a smooth texture that's rich but not heavy. Each spoonful gets better with melted cheddar garnishing the top.
You notice the salty and peppery notes kickin' in, making it balanced and just right for chilly nights or cozy dinners. That broth depth you get from the pressure cooker makes every bite more satisfying.
The melted cheese bubbles on top a bit like a little crust of comfort you didn't know you needed. It's the kind of flavor that takes you back to good times and filling up with something tasty and simple.
How to Store This for Later
Got leftovers? No worries, this soup stores super well. Pour it into airtight containers and pop 'em in the fridge for up to 3 days. Reheat gently to keep that creamy texture intact.
If you wanna keep it longer, freeze the soup without the cheddar garnish. Freeze in portions using freezer-safe containers or heavy-duty freezer bags. Thaw it overnight in the fridge before warming it up slow on the stove.
You can also freeze the shredded cheddar cheese separately in a small baggie. That way you always got fresh cheese to top your soup when reheated.
When reheating from frozen, make sure you warm the soup low and slow, stirring occasionally so it doesn't scorch or separate. The sealing ring on your pressure cooker is also great for reheating as it maintains even temperature, just don't pressure cook it again, just use the sauté or keep warm setting.
The FAQ Section You Actually Need
- Can I use yellow onions instead of sweet onions? Yes, yellow onions work just fine! They might be a bit sharper than sweet onions but still tasty.
- What's the advantage of natural release versus quick release? Natural release lets the pressure drop slowly which keeps soup silky and prevents splatter. Quick release might be faster but risks tough or bubbly soup.
- Do I have to use Velveeta cheese? Velveeta melts easily and adds creamy texture but you can substitute with other processed cheese cubes. Just expect a slight flavor difference.
- Can I make this soup vegetarian? You can swap chicken broth and bouillon for vegetable versions. Just check they're rich enough so broth depth stays good.
- How important is the sealing ring when cooking? It's super important cause it holds steam tight so the pressure can build and flavors intensify. Without it, you wouldn't get the same soup quality.
- Is the soup safe to pressure cook in a regular pot? Nah, you gotta use a pressure cooker for this recipe because it's about building pressure and that signature broth depth you get only with sealed steam. Regular pots just can't do that right.
