Growing up in a household where weeknight dinners needed to be both filling and fast, I developed a special appreciation for one-pot meals that could bring everyone to the table with minimal fuss. This hamburger noodle casserole has evolved in my kitchen over countless Tuesday nights when I needed something comforting but didn’t have hours to spend cooking. The recipe started as my mother’s stovetop version, but I’ve adapted it for the Instant Pot, streamlining the process while keeping all the homey flavors intact.

My family gathers around this dish with the same enthusiasm today as they did when I first started making it. There’s something about the combination of tender egg noodles, savory beef, and that touch of tangy mustard that just feels like home. I’ve photographed this casserole countless times at my dining room table, and it never fails to bring back memories of my childhood kitchen – warm, inviting, and always smelling of something delicious.

Why This Recipe Became a Family Favorite

What makes this hamburger noodle casserole special isn’t fancy ingredients or complicated techniques – it’s the thoughtful balance of flavors and textures that come together in one pot. The spicy brown mustard and tomato sauce create a depth that elevates it beyond a basic pasta dish, while the sweet corn adds little bursts of brightness throughout.

I’ve tinkered with this recipe for years, trying different noodle types and seasoning combinations. The wide egg noodles hold up beautifully to pressure cooking, maintaining their texture without becoming mushy. And that five-minute natural release? That’s the sweet spot I discovered after several test batches – it allows the noodles to finish cooking perfectly while absorbing all those savory flavors.

What You’ll Need

Ground beef: Lean ground beef (93/7); I’ve found leaner beef works best here since we’re not draining the fat completely, allowing some to flavor the dish without making it greasy

Onion: Diced; the foundation of flavor that mellows beautifully during cooking

Kosher salt, black pepper, garlic powder: My simple but effective seasoning trio that enhances without overwhelming

Beef broth: The cooking liquid that becomes our sauce; I’ve tried chicken broth too, but beef broth creates a richer flavor profile

Egg noodles: Old-fashioned wide noodles; they hold their shape wonderfully while soaking up the savory broth

Spicy brown mustard: A secret ingredient that adds a tangy depth; yellow mustard works in a pinch but lacks the same complexity

Ketchup: Just enough to add a touch of sweetness and acidity

Tomato sauce: Creates body in our sauce without making it too heavy

Frozen sweet corn: I love the pop of sweetness; no need to thaw beforehand

Sharp cheddar cheese: Adds creamy richness at the end; I’ve found sharp cheddar stands up best to the other flavors

Let’s Get Cooking

Start with browning
Turn your Instant Pot to sauté and wait for that “HOT” indicator – patience here makes for better browning. Add the beef, breaking it up as it cooks, then add your onions. I like letting them cook together so the onions can absorb some of that beefy flavor. After browning for about 5 minutes, drain most but not all of the grease – a little bit adds flavor. Season with salt, pepper, and garlic powder, stirring to distribute evenly.

Create the foundation
Pour in the beef broth, making sure to scrape the bottom of the pot thoroughly. This step isn’t just about preventing the burn notice – it’s about incorporating all those browned bits of flavor back into your dish. Turn off the Instant Pot after scraping.

Layer with care
Sprinkle the egg noodles evenly across the broth – I’ve found this even distribution helps them cook more uniformly than stirring them in. Then add your mustard, ketchup, tomato sauce, and corn. I don’t stir at this point, which might seem counterintuitive, but I’ve learned through many test batches that layering these ingredients creates the best texture in the final dish.

Pressure and patience
Secure the lid, set the valve to sealing, and cook on manual/pressure for 5 minutes. The magic happens during the 5-10 minute natural release afterward – this resting period allows the noodles to finish cooking perfectly without becoming mushy. I discovered this timing through trial and error in my kitchen, and it makes all the difference in the final texture.

Finish with creaminess
After releasing the remaining pressure, remove the lid and give everything a good stir. The sauce will seem a bit thin at first, but once you stir in the cheese, it all comes together beautifully. I sometimes take a quick photo by my kitchen window at this point – the way the cheese melts into the sauce makes for a beautiful moment.

Make It Your Own

When my son went through his “spicy everything” phase last year, I started adding a few dashes of hot sauce and a sprinkle of red pepper flakes. The heat balances wonderfully with the sweet corn and tangy sauce.

For Sunday family dinners, I often make a slightly more indulgent version with half ground beef and half Italian sausage. The fennel and herbs in the sausage add another layer of flavor that pairs beautifully with the tomato base.

During summer, when my garden is overflowing with zucchini, I dice one small zucchini and add it along with the corn. It adds nutrition and a tender-crisp texture that lightens the dish while still feeling comforting.

What I’ve Learned

Don’t skip the natural release period. I tried quick-releasing the pressure in my early tests, and the noodles weren’t quite done, leaving us with an al dente dinner that wasn’t what I was aiming for.

The spicy brown mustard might seem like an odd addition, but it’s the ingredient that gives this dish its distinctive flavor. I discovered this by accident when I was out of yellow mustard one night, and now I wouldn’t make it any other way.

If your sauce seems too thin after stirring, let the casserole sit for about 5 minutes with the lid off. I’ve found the noodles continue to absorb liquid, and the sauce thickens beautifully as it cools slightly.

For meal prep, this casserole reheats wonderfully. I often make it on Sunday afternoons while I’m photographing other recipes by my dining room window, then portion it into containers for easy weekday lunches.

Frequently Asked Questions

Can I use ground turkey instead of beef? → Absolutely! I’ve made this with ground turkey many times. Just add an extra tablespoon of olive oil when browning since turkey is leaner.

What if I don’t have an Instant Pot? → This works beautifully on the stovetop. Brown everything as directed, then simmer covered for about 15-20 minutes until the noodles are tender, stirring occasionally and adding more broth if needed.

Can I add vegetables? → Definitely! I’ve added diced bell peppers, peas, and even chopped spinach stirred in at the end. Just be mindful that watery vegetables may thin your sauce.

My family doesn’t like spicy foods. Can I skip the spicy brown mustard? → You can use regular yellow mustard instead. The dish won’t have quite the same depth, but it will still be delicious. I wouldn’t omit the mustard entirely, though – it provides a tanginess that balances the richness.

How long does this keep in the refrigerator? → In my experience, it stays delicious for up to 4 days stored in an airtight container. The noodles do absorb more liquid as it sits, so you might want to add a splash of broth when reheating.
