For most standard 1/4–1/3 lb frozen beef patties, plan on about 14–20 minutes on a preheated medium/medium‑high grill, but always cook to a safe internal temperature of 160°F for beef.

Quick Scoop

  • Preheat your grill to medium or medium‑high, about 350–375°F.
  • Put the patties on frozen , don’t thaw, and close the lid.
  • Total grill time: usually 14–20 minutes depending on thickness, grill type, and how well‑done you like them.
  • Flip every 4–6 minutes to avoid burning and to cook evenly.
  • For rare/medium‑rare on higher‑end beef, you’ll often be in the 10–15 minute range; for well‑done, expect closer to 18–20+ minutes.
  • Always finish by checking the internal temp:
    • Beef: 160°F internal
    • Turkey/veggie patties: 165°F internal

Simple timing example (375°F grill)

  • Rare: ~10 minutes total.
  • Medium‑rare to medium: ~15 minutes total.
  • Well‑done: 20+ minutes.

Think of frozen burgers as a “low‑stress weeknight grill”: lid closed, flip a few times, and let the thermometer be the final judge instead of the clock.

Mini sections

1. Basic step‑by‑step

  1. Preheat grill to 350–375°F (clean the grates first).
  1. Place frozen patties on the hot grates, not touching.
  1. Close lid and cook 4–6 minutes.
  2. Flip, season the browned side, cook another 4–6 minutes.
  1. Continue flipping every 3–5 minutes until they reach 160°F internal.
  1. Add cheese for the last 1–2 minutes if you like, then rest 2 minutes off the grill.

2. Different patties, slightly different times

  • Thin, fast‑food‑style patties: often closer to 10–12 minutes total.
  • Standard frozen patties (about 1/3 lb): 14–20 minutes.
  • Branded patties like BUBBA burgers: often cooked 4–6 minutes per side on medium‑high, then checked for 160°F.

Forum & “real‑world” tips

Public grilling forums like r/grilling often suggest using a simple flip schedule (for example: 5 minutes, flip; 10 minutes, flip; final 5 minutes) and adjusting based on how fast your grill runs and how the outside looks. In practice, backyard grillers mix these “rule‑of‑thumb” timers with a thermometer check and a two‑zone setup (sear over direct heat, then finish on a cooler side) for more control and fewer flare‑ups.

SEO bits you asked for

  • Focus phrase worked in: how long to grill frozen burgers at 350–375°F is typically 14–20 minutes, with rare around 10 minutes and well‑done taking 20+ minutes, depending on patty size and grill type.
  • Current context: as of early 2026, quick‑cook methods (air fryers, Ninja‑style indoor grills) are trending, but classic outdoor grilling times for frozen patties still hover in that same 10–20 minute window at medium‑high heat.

TL;DR: Set your grill to medium/medium‑high, cook frozen patties about 14–20 minutes total, flipping every 4–6 minutes, and use a thermometer to hit 160°F for safe, juicy burgers.
