My grandma's kitchen was always filled with incredible aromas during holidays, thanks to this three-ingredient brisket. When I cook it now, the mix of soft meat, tangy sweet ketchup, and flavorful onion soup mix works just as well as it did back then. The coolest thing? You can't mess it up - it turns out fall-apart tender every time with just three basic ingredients.
Effortless Kitchen Wonder
The magic happens when these everyday items come together. The ketchup turns into this amazing sticky glaze while the soup mix adds deep flavors you'd think came from tons of herbs and spices. No one ever guesses it's only three ingredients - they're always trying to figure out what secret stuff I've added.
What You'll Need
- The flavor boost: A packet of onion soup mix does all the heavy lifting.
- Your sauce base: Just regular ketchup from your fridge will do.
- The meat: Get a nice brisket, try to find point cut with good fat running through it.
Let's Get Cooking
- Low and slow:
- Wrap everything tight in foil and cook about four hours till it's soft enough for a fork to slide through.
- Mix your magic:
- Blend the ketchup and soup mix together until smooth; coat your brisket completely.
- Prep your meat:
- Put that brisket with the fat on top in your largest roasting pan.
- Start your oven:
- Heat it up to 300°F while getting everything else ready.

My Kitchen Secrets
I've made this so many times I've got all the tips. That fatty point cut ends up super tender. Figure about a pound for each person since it shrinks during cooking. Don't slice it right away - let it sit so the juices stay in. I sometimes throw in some sliced onions, but honestly, it doesn't need anything extra.
Time to Serve
Cut your brisket across the grain in thick half-inch slices; pour all that yummy pan juice over top. We usually have this with buttery mashed potatoes or good bread to mop up the sauce. Add some cooked veggies on the side and you've got a full meal ready to go.
Plan Ahead
You know what's great about this dish? You can fix it early. Cook it all the way, let it cool enough to slice, then put it back in with all that tasty juice. When you're ready to eat, just warm it up in the oven with the cover on. The meat stays super juicy, and it actually tastes even better.
Saving Some For Later
This dish freezes really well. I often cook extra just to have some ready for busy days. Pack it up with plenty of sauce and it'll keep for months in the freezer. Just don't rush the thawing - it needs about two days in your fridge, then warm it slowly in the oven.

More Than Just Dinner
This three-ingredient brisket has turned into our family tradition. It's what shows up at every holiday, what my friends ask for when they come over, and what my kids want to learn to make before moving out. There's something about how easy it is yet how amazing it tastes that really brings folks together. Seeing everyone's face light up when they take that first bite - that's why I love cooking.
Frequently Asked Questions
- → Why leave the brisket to rest after cooking?
It gives the juices time to spread evenly, so the meat stays juicy and slices easier without getting dry.
- → How should I cut the brisket?
Slice across the muscle lines, not along them. Going against the grain keeps your slices soft and easy to chew.
- → Can I use a slow cooker for this?
Of course. Cook everything on low heat for 8-10 hours in the slow cooker. Just follow the same steps for prepping.
- → Why is point or deckle brisket better?
These cuts have more fat inside, which helps keep the meat moist and adds rich flavor during long cooking sessions.
- → Can leftover brisket be frozen?
Yes, wrap it tightly and store it in the freezer for three months. Thaw in the fridge overnight and reheat gently with some sauce to keep it tasty.
