Eye of Round Roast
at 325°F
The answer
1 hr 15 min – 1 hr 40 minat 325°F
Plan on 22 to 28 minutes per pound in a 325°F oven. A 3.5 lb eye of round roast lands around 1 hr 15 min – 1 hr 40 min. Done is 145°F on a food thermometer, plus a 15-minute rest — never the clock alone.

USDA safe zone — 145°F and above
Done is a temperature, not a time. Every figure on this page is a planning range; the green band is the only part that decides. For an eye of round roast it opens at 145°F and a 15-minute rest.

How this is worked out
- Anchor. Start from what USDA FSIS publishes for an eye of round roast — its safe minimum internal temperature of 145°F, and the FSIS roasting timetable where one exists for this cut.
- Rate. Convert the anchor into a planning rate at 325°F: 22–28 min/lb, cross-checked against at least three independently published sources.
- Scale. Multiply that rate by your weight. A 3.5 lb piece lands at 1 hr 15 min – 1 hr 40 min; the range is widened to cover source disagreement rather than averaged into false precision.
- First check. The first thermometer reading is set at 85% of the low end of the range — early enough that an under-reading costs nothing and a late one cannot cost the meal.
- Gate. The time is only a plan. It is not done until a food thermometer reads 145°F in the thickest part, then rests about 15 minutes. Time never overrides temperature on this site.
- Round. Every printed figure is rounded to the nearest 5 minutes; precision beyond that would be invented.
plan_low = weight_lb × 22 min/lb
plan_high = weight_lb × 28 min/lb
first_check = plan_low × 0.85
DONE ⟺ internal_temp ≥ 145°F AND rest ≥ 15 min
(USDA FSIS — the gate, not the clock)

Time by weight at 325°F
Planning ranges for a fully thawed, fridge-temperature eye of round roast. The right-hand column is when to take the first thermometer reading.
| Weight | Estimated time at 325°F | Check thermometer from |
|---|---|---|
| 2 lb | 45 min – 55 min | 35 min in |
| 2.5 lb | 55 min – 1 hr 10 min | 45 min in |
| 3 lb | 1 hr 5 min – 1 hr 25 min | 55 min in |
| 3.5 lb | 1 hr 15 min – 1 hr 40 min | 1 hr 5 min in |
| 4 lb | 1 hr 30 min – 1 hr 50 min | 1 hr 15 min in |
| 4.5 lb | 1 hr 40 min – 2 hr 5 min | 1 hr 25 min in |
| 5 lb | 1 hr 50 min – 2 hr 20 min | 1 hr 35 min in |
Start checking the internal temperature well before the low end of the range — an early check costs nothing; a late one costs the meal. Done means 145°F on a food thermometer.

When it is actually done
145°F internal
The USDA FSIS safe minimum internal temperature for this cut is 145°F, followed by a rest of about 15 minutes. The clock estimates; the thermometer decides. Every time on this page is a planning range, not a doneness test.

Doneness temperatures
| Doneness | Internal temp | |
|---|---|---|
| Rare | 120–125°F | below the USDA minimum |
| Medium-rare | 130–135°F | below the USDA minimum |
| Medium | 135–145°F |
USDA FSIS recommends a minimum of 145°F with a 15-minute rest for whole cuts. Rare and medium-rare sit below that guideline — a personal choice many cooks make with fresh, well-handled meat, listed here because these are the temperatures cookbooks and restaurants use.

The clock tells you when to start looking. The thermometer tells you when to stop.
What the ledger does not tell you
- This is the classic deli-roast-beef cut: cook to medium-rare at most, rest fully, then slice paper thin against the grain — thick slices of round are shoe leather.
- Some cooks prefer the 'closed-oven' method (500°F for 5 min/lb, then oven off for 2 hours untouched); it works, but only the timetable above is oven-independent.
- A lean round roast has no marbling to hide behind — the thermometer matters more here than on a rib roast.
Answers people ask
How long does an eye of round roast take at 325°F?
Plan on 22 to 28 minutes per pound at 325°F. A 3.5 lb example takes about 1 hr 15 min – 1 hr 40 min. It is done when the internal temperature reaches 145°F on a food thermometer, not when the clock runs out.
What internal temperature is an eye of round roast done at?
145°F, measured with a food thermometer in the thickest part, then rested about 15 minutes. That is the USDA FSIS safe minimum.
Is 325°F a good temperature for an eye of round roast?
It is one of 2 temperatures this site publishes for this cut (325°F, 350°F). It is the most commonly used.

Where these numbers come from
Ranges are anchored to USDA FSIS published timetables where they exist, and derived from that anchor plus cross-checked published sources where they do not — widened to cover the disagreement between sources rather than split down the middle. The full reasoning is on the method page. If a figure here looks wrong, say so — corrections are prioritised.
