Choosing between the Ninja AG301 and DG551 comes down to space, features, and how often you cook for family. I’ve used both in my kitchen here in Austin, Texas. Grilling outside isn’t always easy in the summer heat.
The AG301 gave me a compact way to grill indoors. The DG551 added more room and a smart thermometer that saved me from guessing. After testing both, I’ll share what works, what doesn’t, and which one I recommend based on your needs. Let’s break it down.
Ninja AG301 Review
I’ve been using the Ninja AG301 for quick family dinners, and it has saved me more times than I can count. It works as a grill, air fryer, and oven in one. The big win for me is grilling indoors without smoke filling the kitchen. I’ve cooked chicken straight from frozen, and it still came out juicy with grill marks in under 25 minutes.
The size is just right for two to three people. I can stretch it for a family meal, but it’s tight. It heats fast, cooks even, and I don’t need to turn on my big oven. For busy weeknights, that’s a game-changer.
What I Like
- Heats up fast, so dinner starts on time.
- Grill marks taste and look like outdoor grilling.
- Air fry basket makes fries crisp without the oil.
- Easy cleanup with dishwasher-safe parts.
- Compact size fits on my counter without taking over.
What Could Be Better
- Cooking space works for small families but feels tight for big groups.
- No built-in smart thermometer, so I use my own.
- A bit heavy to move if you plan to store it often.

Ninja DG551 Review
I tried the Ninja DG551 when I wanted more space than the AG301. The extra room stood out right away. I could grill four chicken breasts at once without crowding, which made family meals easier. The built-in smart thermometer is a real upgrade. It shows me when food reaches the right temp, so I don’t need to guess.
The DG551 still cooks fast like the AG301, but the smart features give more control. I grilled salmon last week, and it came out moist in the middle with crisp edges. I didn’t need to stand over the grill, which made dinner stress-free.
What I Like
- Larger cooking space fits family-size meals.
- Built-in smart thermometer takes out the guesswork.
- Even cooking, whether grilling, roasting, or air frying.
- Strong build feels durable for long use.
- Cleanup is easy with nonstick, dishwasher-safe parts.
What Could Be Better
- Bigger size takes more counter space.
- Heavier than the AG301, not great if you move it often.
- Price is higher, but fair with the added features.

Recommendation
I’d recommend the Ninja DG551 to families or anyone who loves the built-in smart thermometer. It’s great for people who grill often and want bigger portions cooked even without guesswork. Busy parents will enjoy how it takes stress out of meal prep. If you live in a small apartment or only cook for one or two people, the smaller Ninja AG301 may fit better. For me, the DG551 feels like the “all-in-one” grill that makes weeknight meals simple and reliable.
