Overview

The Primo XL Oval 400 ceramic grill (778) is one of Primo’s most popular ceramic grills and no wonder. It offers the largest cooking area, and Primo’s Patented Oval Design creates extremely high cooking flexibility and efficiency. The Primo Oval 400 is perfect as a primary grill or to complement your current gas grill, electric grill or smoker. With over 400 square inches of cooking surface, it's deceptively large when it comes to the amount of food that can be cooked on it. Available as “grill only” for built-­in applications in outdoor kitchens, or with a variety of Primo Grill Tables and Cart options (sold separately). The Primo Oval XL 400 smoker is constructed of premium-­grade ceramics, a cast iron top vent, easy-­to-­read thermometer, two-­piece reversible porcelain-coated cooking grates, and a stainless steel lower draft door. Made in the USA this Primo Grill comes with a Limited Lifetime Warranty backed by a 20­-Year Guarantee on the ceramics. Primo’s Patented Oval Design delivers far more cooking flexibility than round standard-sized ceramic grills, by being able to simultaneously cook with two distinct cooking zones. Grill steaks on the direct side and roast tender foods like fish, seafood and vegetables on the indirect side at the same time without the tender food being overcooked and charred (indirect cooking for baking, roasting, and smoking requires the heat deflector racks and plates - sold separately). Let’s face it, most food is not round. The patented oval design creates an extremely efficient cooking space so you can cook more food at the same time. When it comes to adding a kamado grill to your backyard, look no further than the Primo XL 400 Oval Large Charcoal Ceramic Kamado Grill.

Questions About This Product

Can I burn wood as fuel in my Primo grill or only charcoal? Or does wood burn too hot? Will it stain the ceramic in my Primo Grill? What if I want to get that "smokey" flavor?

We recommend using only Primo 100 Percent Natural Lump Charcoal (Model #608) for your Primo Charcoal Grill, as it is an environmentally-friendly special blend of charcoal that is free of tars and other harmful chemicals. Burning wood in your Primo grill can release excess toxins and soot that get absorbed into the ceramic of your Primo Grill and your food. If you would like to add extra flavor to your food, you can place your foods on our special Cedar Planks soaked in wine, juice, or other flavorful liquid, and place the cedar plank on the grilling grate. The flavors of the liquid will get absorbed into your food and it will add a sweet, smoky or spicy aroma that results in deliciously moist food that is rich in flavor. You can also use small pieces of wood chips or chunks to add the smokey flavor to your food, but you should not use wood as the primary fuel source for your Primo Grill.

1. Does this come with a rack?
2. What other accessories should I consider?

1. The Primo Oval XL 400 comes with an industry-standard porcelain-enamel cooking grate included. An extended cooking grate (Model #332) can be purchased and it will increase your cooking surface by 30% by creating an additional cooking surface above the standard grate. If you purchase two of these extended grates, they can both be used at the same time to extend the cooking surface by 60%. Or, if you would like, you can upgrade the standard porcelain-enamel cooking grate with two (2) of the Primo Cast Iron Searing Cooking Grates (Model #361).

2. The Primo Half-Moon Cast Iron Dual-Purpose Griddle for Primo Oval XL (Model #360), Primo 16-Inch Glazed Ceramic Baking Stone (Model #338), and Primo Curved Cypress Kamado Table for Primo Oval XL (Model #600) are great accessories to consider for the Primo Oval XL 400.

Reviews for Primo Oval XL 400 Charcoal Ceramic Kamado Grill

The Grill is Outstanding

I have grilled for more than 20 years and bought the Primo 400XL about seven years ago after owning 2 weber grills (1) platinum gas and (1) charcoal. I refurbed the gas grill and gave it away and sold the charcoal one. I can't say enough about the Primo as I was minutes away from buying a Green Egg and at the last minute could not walk away from the value and design of the Primo. I am an Engineer and was intrigued by the design and quality of the Primo at first glance and boy was I ever right as many of my friends have Green Eggs and they all envy my Primo. I don't want to say anything negative regarding the Green Egg as I believe it is a great Grill, however; time and time again I believe there are many more options in terms of offset cooking and ease of use. I put many money where mouth is and I've purchase a second one as my family is a large family and finally got to the point where I was not able to keep up with the demand. I am pleased and highly recommend the grill.

This is the alpha male of Kamado Cookers

I looked at several "XL" (24" grid) cookers. I was consdering the Kamado Joe Big Joe, the Big Green Egg XL and the Weber Summit. Then somehow I sort of stumbled on an ad for this grill. I had never heard of it, but the more I looked into it, the more intriguing it became. I picked one up in a cart and couldn't be happier. you'll read this a lot, but the oval shape really does give you a lot of advantages when it comes to setting up two zone cooking. The Being an oval shape also lends well to very large pieces of meat, especially long cuts like full packer briskets or multiple slabs of ribs. Primo makes a bunch of great accessories as well including a nice variety of grates and even solid cast iron plates that can turn it into a griddle. Best of all, the entire product lines is made in the USA, not in Mexico or China.

6 yrs and going strong

I researched every ceramic grill that I could before I bought my Primo XL in 2013. The hip thing was to buy a BGE... a lot of my friends had one. After my research, it made more sense to buy the Primo due to it's versatility. I have had it for 6 years and I wouldn't change my purchase at all. I LOVE IT!!!

The Primo Oval XL is the best grill/smoker I've found!

I've owned my grill for a yr now and probably have had 100+ cooks on it. Lots of grilling, roasting, baking (pizzas) and more recently some long low and slow smoking. I researched for a good while before buying, I cooked on the 3 biggest selling brands, BGE, Primo, and KJ. My finding is you really can't go wrong with any of the top branded ceramic grills. The Kamado Joe offers the best value because you get more accessories included than with the BGE or Primo. That said, the versatility of the Primo Oval XL is unrivaled...true dual zone cooking from the firepit up and that separates it from the other two. For me it's not so much the Primo Oval XL is better than the KJ or BGE...it's more about where it's made (USA) what it can do that the other round ceramic grills cannot. I'm an empty nester and bought the Oval XL...the extra space comes in handy.

Primo Oval XL = Prime Grill Quality and Customer Service

Primo Ceramics by far are of the highest quality compared to BIG Green Egg and Kamado Joe. The shape has many advantages as you can truly do two zone cooking unlike with rounded kamados; in addition, the bottom vent is located close to the left side making the airflow start at that side and then making it around which kind of reminds me of the offset smoker. That design will produce better meats. Seems like Primo always evolve, and they have cracked Firebox instead of a whole one. I have also heard they might improve their hinge in the future that would be big improvement since that dome weights almost as much as the base, very heavy. And they are developing stainless steel grates which is also nice. I have had quite a hassle with getting primo grill due to shipping issues, but what surprised me is the responsiveness of both, Primo and BBQ Guys. You cannot go wrong with Primo Grill, they are champions at ceramic kamados at so many levels, always improving and are made in the USA which speaks - quality due to all the quality controls and environment laws & regulations we have in this country.

Great Grill/smoker

I have had the Primo Oval XL for about six months and use it every weekend as well as many week nights. The weekends are typically spent smoking some pork butt or brisket...during the week we grill steaks, burgers, salmon....it is easy to use, I love this grill.

Primo Oval XL

The unit is well made as is the metal cart we got with it. We had one cross threaded bolt that we could not use but overall it went together without a problem. The sales and service people were quick to respond to any questions we had. The pork shoulder we smoked was tender and moist. It was better than the pork we have been smoking on our gas grill. The temperature was a lot easier to control than I thought it would be and we didn't use a lot of charcoal for 12 hours of smoking. We are very happy with the product.

Gave away the big gas grill!

The versatility and quality of the Primo is superb! We use this 3-4 times per week. With the divider, offset cooking is a breeze. Go on the Primo forum for recipes & user tips from other aficionados. This is an investment that pays big dividends in excellent tasting food.

Primo Oval XL is Xlent!!!

I have grilled and smoked all my life. My Dad bought his first Weber in 1972. I love to smoke and have competed in many contests. I bought my Primo XL 6 years ago. It is the most efficient and Versitile unit available. Buy it! It does it all. I cook the entire meal on it without a sweat.

Best size and most versatile ceramic cooker, period!

I definitely did my research ahead of time and this is the cooker I choose. My only complaint is I wish I would have purchased it sooner. If you love to BBQ and grill this is a must. First you need to be sold on a Komodo type cooker i.e., ceramic. From there, you have the choice of about five brands. Ceramic in general: Pros - Well insulated so food does not dry out - Keeps flavor in and you can taste a difference - Extremely efficient with charcoal - Can grill at a seating 700 degree or smoke at 150 degrees and everything in-between - Keeps temperature even an consistent - Due to large ash space and fuel conserving efficiency, you can reuse old coal for next cook. Just light it and let it warm up while you prepare your food; almost as simple as gas. Cons: - Heavy - Pricey - You will become addicted to outdoor cooking! Unique differences offered by the Promo Oval. 1. Much larger cooking area, the Green Egg, as well as other traditional shapes which are only 18" and are very limited. "Have you ever cooked on an 18" Weber Kettle it's just inconveniently too small". 2. Extra extended cooking racks for even more space are available. 3. Iron divider that fits in the fire box for true indirect cooking; great for steaks or anything in that matter where, you want indirect and direct cooking at the same time 4. A great user Forum site full of supporting users, as well the people at Primo are super helpful and knowledgeable. Lastly, the great thing about this cooker is the ease of use; I've cooked a brisket for 18 hours and never needed to add charcoal or even lift the lid during the entire cook! I truly believe Primo is the Cadillac of the "ceramic cookers". Another nice feature is if you add lots of coal at first, due to its efficiency you can just re-light what's left over from the last cook and a few more times depending on what your cooking; it's nice to just to go out and light it without cleaning ashes an pulling out the bag each time! I have had mine for close to five years now and still love it I now cook outdoors 3 to 4 days a week now:)
