Set ham on a trivet with water, pressure-cook by weight, and heat the ham to a safe internal temperature before serving.
Short on oven space or time? A pressure cooker can warm a spiral ham fast and keep it juicy. The method is simple: add the right amount of liquid, set the ham on a trivet, lock the lid, cook by weight, and confirm doneness with a thermometer. This guide explains setup, timing, temperature targets, and glaze options so you can plate tender slices without guesswork.
How Do You Cook A Ham In A Pressure Cooker? Step-By-Step
Here’s the clean, repeatable process home cooks use for pressure-cooker ham. The sequence below assumes a 6- to 8-quart electric model with a trivet.
Gear And Ingredients You Need
- 6–8 qt electric pressure cooker with trivet
- Pre-cooked spiral-sliced or unsliced ham that fits below the max fill line
- 1½–2 cups liquid (water, stock, or juice; see size notes below)
- Foil, if you want to wrap to hold glaze
- Glaze (brown sugar + juice/maple/honey) or packet from the ham
- Instant-read thermometer
Set Up The Pot
- Insert the trivet. Add liquid to generate steam. Most 6-quart models need ~1½ cups; many 8-quart models need ~2 cups. Check your manual’s minimums.
- If using glaze, make a snug “foil boat” around the ham to keep juices close. Leave the top open so steam can circulate.
- Lower the ham onto the trivet. Seal the lid. Set to High Pressure.
Cook Time Guide By Ham Type
Because spiral hams are already cooked, you’re reheating to a safe serving temperature without drying it out. Unsliced or boneless roasts may need a few extra minutes. Always finish by checking internal temperature in the thickest part, away from bone.
| Ham Type | Typical Size | Starting Cook Time Guide* |
|---|---|---|
| Spiral-Sliced, Bone-In | 4–8 lb | ~2 minutes per pound; natural release 10–15 minutes |
| Spiral-Sliced, Boneless | 3–6 lb | ~2 minutes per pound; natural release 10 minutes |
| Half Ham, Unsliced (Butt/Shank) | 4–6 lb | ~3–4 minutes per pound; natural release 15 minutes |
| Boneless Ham Roast (Pre-Cooked) | 2–4 lb | ~3 minutes per pound; natural release 10 minutes |
| Picnic/Shoulder (Smoked, Pre-Cooked) | 3–6 lb | ~3–4 minutes per pound; natural release 15 minutes |
| Ham Steaks (Thick) | 0.5–1 lb | 1–2 minutes total; quick release |
| Fresh (Uncured) Ham Roast | 3–6 lb | Cook by temperature; start ~4 minutes per pound; check often |
| Leftover Slices (Reheat) | — | 0–1 minute; quick release; check 165°F for leftovers |
*Timing is a starting point. Size, shape, and starting temperature change results. Always confirm internal temperature (see “Safe Temperatures” below).
Finish With A Glaze
- Lift the ham to a platter. Switch the cooker to Sauté.
- Whisk 1 cup cooking juices with ¼–½ cup brown sugar and 1–2 tablespoons maple or honey. Simmer to a syrup. If you like it thicker, whisk in 1 teaspoon cornstarch in cold water and simmer 1–2 minutes.
- Brush the glaze over the slices. For extra sheen, broil the ham in the oven for a few minutes while you watch closely.
Safe Temperatures And Liquid Minimums
Food safety is non-negotiable. Pre-cooked ham needs to be heated to 140°F if it was packaged in a USDA-inspected plant; other cooked hams and leftovers should reach 165°F. Fresh (uncured) ham should reach 145°F with a short rest. Link these targets to your thermometer checks, not the clock.
Pressure cookers also need enough liquid to build steam. Most modern 6-quart electric models call for at least ~1½ cups; many 8-quart models call for ~2 cups. Keep the total contents below the 2/3 fill line when pressure cooking.

Thermometer Checks That Save Dinner
- Insert the probe into the thickest part, away from bone.
- Spiral hams: spot-check between the center and outer slices.
- If you’re under target, lock the lid and add 2–3 minutes more. Repeat as needed.
Close Variant Keyword: Cooking Ham In A Pressure Cooker (Timing, Liquid, And Doneness)
This section frames the same task using a close variant of the main phrase. The steps are identical: measure liquid, set the ham on a trivet, pressure-cook by weight, and check temperature. That’s the core logic behind cooking ham in a pressure cooker with low risk of dry spots.
Why Weight-Based Timing Works
Hams vary in diameter, density, and slice pattern. Weight-based timing gives you a workable baseline, then the thermometer closes the gap. Spiral-sliced warms faster because steam can get between slices. Unsliced and boneless roasts take longer.
Natural Release Vs Quick Release
Let the pot sit for 10–15 minutes after the timer for most whole hams. This “natural release” keeps juices inside and prevents splatter. Quick-release suits small portions or steaks because they heat through quickly. If you see a burst of steam and bubbling juices, back off and let pressure drop further before opening.
How Do You Cook A Ham In A Pressure Cooker? Troubleshooting
The exact phrase “how do you cook a ham in a pressure cooker?” comes up a lot, and the snags are predictable. Use this checklist if your first test run misses the mark.
Ham Is Warm Outside, Cool In The Center
- Add 2–5 minutes at High Pressure, then natural release for 10 minutes.
- Stand the ham cut-side down on the trivet to expose the dense area to steam.
- Verify liquid is at or above your model’s minimum so pressure builds properly.
Ham Feels Dry
- Spiral hams dry faster. Wrap in a foil “boat” and pour glaze or juice over the top before cooking.
- Cut thicker slices. Thin edges lose moisture on the platter.
- Swap to natural release and avoid long broil times after glazing.
Pot Won’t Reach Pressure
- Measure liquid. Many 6-quart models need ~1½ cups; 8-quart often need ~2 cups.
- Check the silicone ring and steam-release parts. Seat everything firmly.
- Large hams must sit below the max fill line; trim as needed.
Glaze Is Thin
- Reduce on Sauté until syrupy, or thicken with a small cornstarch slurry.
- Brush, rest 5 minutes, then brush again for a glossy coat.
Model-By-Model Liquid Minimums (Quick Lookup)
Keep a tiny sticky note inside your cabinet with these common figures. Always defer to your exact manual.
| Pot Size | Minimum Liquid | Fill Rule |
|---|---|---|
| 3 qt (Mini) | ~1 cup (250 mL) | Do not exceed 2/3 when pressure cooking |
| 6 qt | ~1½ cups (375 mL) | Do not exceed 2/3 when pressure cooking |
| 8 qt | ~2 cups (500 mL) | Do not exceed 2/3 when pressure cooking |
Sample Timelines You Can Trust
Spiral-Sliced, Bone-In (5 lb)
Add 1½–2 cups liquid. Cook 10 minutes (2 minutes × 5 lb). Natural release 10–15 minutes. Spot-check several slices; aim for 140°F. Brush glaze and rest a few minutes before carving.
Unsliced Half Ham (5 lb)
Add 1½–2 cups liquid. Cook 18 minutes (about 3–4 minutes × 5 lb). Natural release 15 minutes. Probe the center; if not at target, add 3 minutes and recheck.
Leftover Chunks Or Thick Steaks
Add 1 cup liquid on the trivet. Cook 1–2 minutes, quick release, then verify 165°F since leftovers need a higher reheat point.
Food Safety, Holding, And Leftovers
Hold cooked ham above 140°F if you’re serving later. Chill leftovers within two hours. Reheat leftovers to 165°F. These numbers keep the meal safe on busy holidays and weeknights alike.
Flavor Boosts That Work In A Pressure Cooker
Simple Brown Sugar Glaze
Whisk brown sugar with pineapple juice or apple cider. Add a spoon of Dijon for a gentle edge. Reduce on Sauté until it coats a spoon.
Maple-Orange Glaze
Simmer maple syrup with orange juice and zest. Add a pinch of clove or allspice. Brush on, broil briefly, and serve.
Savory Mustard Glaze
Stir whole-grain mustard into stock and honey. Reduce to a shine, then finish with a knob of butter for a smooth finish.
Quick Reference: The Four Rules
- Right size: the ham must sit below the max fill line so the lid can lock.
- Right liquid: measure the minimum for your pot size before you start.
- Right time: start with minutes per pound; favor natural release.
- Right temp: confirm the correct internal temperature with a thermometer.
Where The Exact Phrase Fits Naturally
If a reader asks “how do you cook a ham in a pressure cooker?” the short, practical reply is this: measure the liquid, set the ham on a trivet, cook by weight, and verify temperature. Add glaze, rest briefly, and slice to serve.
