A soft, sweet, high-fat nut native to North America, closely related to hickory. Sold in halves and pieces, and prone to going rancid quickly.
What it does in a recipe: A buttery, sweet nut that toasts beautifully and provides both crunch and fat to a topping or a filling. Pick the swap that covers that job — the ratios below are written so you can act on them without doing any arithmetic.

4 ways to replace pecans
Walnuts
Closest match
1 cup pecan halves = 1 cup walnut halves
The same size, structure and fat content, so they toast, chop and bake identically. The only real difference is a tannic note in the skin.
Trade-offSlightly bitter where a pecan is sweet, which is noticeable in a pecan pie and invisible in a spiced loaf.
Allergen checkWalnuts are a tree nut, and walnut and pecan are botanically close enough that many people allergic to one react to the other. Check labels for shared processing, and treat a known nut allergy as a clinical matter rather than something to substitute around.
Hazelnuts
Reliable
1 cup pecan halves = 1 cup hazelnuts, toasted and skinned
A comparable fat content with a firmer texture, so they hold their shape in a sticky filling better than a pecan does.
Trade-offFirmer and far more aromatic, and the flavour dominates rather than blending into a caramel or a butter filling.
Allergen checkHazelnuts are a tree nut. Nut processors commonly run several species through the same equipment, so check the packet for shared-line statements. Where the allergy is severe, confirm with the manufacturer rather than relying on labelling.
Toasted sunflower seeds
In a pinch
1 cup pecan halves = 1 cup raw sunflower seeds, toasted
They carry enough fat to toast rich and crisp, and being seeds rather than nuts they are the correct choice for a nut-free household or a school bake sale.
MethodToast dry over medium heat for four or five minutes until golden and fragrant, then cool completely before folding them in.
Trade-offSavoury rather than sweet, and much smaller, so a pecan pie topped with them looks and eats quite differently.
Allergen checkSunflower seeds contain no tree nut or peanut protein and are the standard nut-free replacement. The risk is in packing, not in the seed, so choose a brand that certifies a nut-free facility where the allergy is serious.
Macadamia nuts
Reliable
1 cup pecan halves = 1 cup macadamia nuts, roughly chopped
Macadamias are even higher in fat and share the pecan's soft, buttery quality, so they give the same richness with a rounder flavour.
Trade-offCreamier and milder, and considerably more expensive. They also brown faster because of the extra oil.
Allergen checkMacadamias are a tree nut and share processing facilities with other nuts as a matter of course. Look for cross-contact statements on the packet. A severe nut allergy needs medical guidance rather than a substitution table.
Worth knowing
Pecans have more oil than almost any common nut and go rancid within weeks in a warm kitchen. Store them in the freezer and toast them straight from frozen.
Cooking around an allergy? Diet tags here describe the ingredient itself, not any particular brand. Processed products change formulation without notice and shared production lines are common, so read the label on everything you use. A severe allergy is a medical matter — confirm with the manufacturer or your clinician rather than relying on a substitution chart.
