Diagnose the mixture before cooking. A raw patty that slumps and sticks heavily is a moisture or binder problem; a patty that is firm raw but breaks only during the first flip points more strongly to crust formation.
Symptom matcher
Which one looks most like yours?
Small visual differences can point to very different causes.
Check bean and vegetable moisture.
Check binder amount.
Check how finely the beans were processed.
Try chilling one test patty.
Check browning before turning.
Right now
Can it be saved?
Often, if excess moisture is moderate.
Limit: Large amounts of added binder can make burgers dense or pasty. Very wet vegetables are better dried or cooked down before the final mixture is assembled.

Get to the first clue faster
Answer one question at a time. The result comes from the same reviewed diagnosis data below.
Does the raw mixture look glossy, wet or prone to slumping?
Reduce excess moisture
Wet vegetables or beans can overwhelm the binder.
Likely cause: The vegetables or beans carried too much moistureDoes the mixture crack or fall apart when lifted?
Adjust the binder
The binder may be too low for the moisture level.
Likely cause: There was not enough binder for the moisture levelIs the mixture completely smooth and paste-like?
Keep more coarse structure
Overprocessed beans can make the center pasty.
Likely cause: The beans were processed into a smooth pasteDo freshly shaped patties firm up noticeably after chilling?
Rest or chill the mixture
Hydrated binders and colder patties handle better.
Likely cause: The mixture was not given time to firmDo patties break mainly during the first flip?
Let the crust set
Turning too early can tear a soft patty.
Likely cause: The patty was flipped before the crust setDiagnosis
Check the likely causes
Start at the top, but skip anything that clearly does not match your batch. Evidence labels describe the support for each cause, not a fake probability score.
The vegetables or beans carried too much moisture
The mixture looks glossy, sticks heavily to your hands and slumps after shaping.
Squeeze a spoonful; if it releases visible liquid or spreads rather than holding, moisture is excessive.
Chill the mixture and add a modest amount of dry binder; very wet mixtures may need additional cooked-off moisture.
Drain beans thoroughly and cook watery vegetables before mixing.
There was not enough binder for the moisture level
The raw mixture forms but cracks or squishes apart when lifted.
Cook a small test patty; if it breaks while the flavor is otherwise right, binder is likely insufficient.
Add a small amount of breadcrumbs, oats or flour and rest before re-testing.
Measure the binder and let the mixture rest so it can absorb moisture.
The beans were processed into a smooth paste
The mixture resembles hummus or paste with no visible bean pieces.
Compare the texture with a batch where beans are mashed only until partly broken.
Fold in some coarse cooked grains or chopped nuts if available; otherwise cook gently and handle minimally.
Mash or pulse beans only until chunky.
The mixture was not given time to firm
Freshly mixed patties slump but become firmer after refrigeration.
Chill one test patty for 30 to 60 minutes and compare handling.
Refrigerate the shaped patties before cooking.
Build a rest or chill into the method.
The patty was flipped before the crust set
The first side is pale and sticks when lifted.
Wait until the edges look set and the underside is well browned before trying to flip.
Let the first side cook longer, then turn with a wide spatula.
Use moderate heat and flip once after a firm crust develops.
Don't jump to conclusions
Common misdiagnoses
Kitchen science
What is actually happening?
Successful veggie-burger methods manage water before shaping, retain some coarse texture and use binders such as oats, breadcrumbs, flour or egg. Resting also gives those binders time to absorb moisture.

What we plan to test
Planned tests are shown transparently and are never presented as completed results.
Veggie-burger moisture and binder comparison
A drier mixture with a measured binder and a short rest will hold shape better than a wetter unrested mixture.

Food Network explicitly roasts vegetables to remove moisture and rests the mixture so oats absorb moisture before shaping.
