How to Make Spinach-Pesto Stuffed Chateaubriand With “Broken Spaghetti”

This decadent dish is held together – literally – by a world-famous filet mignon roast: Omaha Steaks Private Reserve® Chateaubriand Roast. Hand-selected by our most experienced master butchers and triple-trimmed to exact specifications, this flawless roast is extra-aged for a minimum of 35 days to maximize flavor and tenderness and is guaranteed to wow the whole table.

Chef’s Tip: This plate-busting Chateaubriand takes between 24 and 48 hours to fully thaw in the refrigerator, so plan your meal ahead of time.

1. Whip Up Some Popeye-Approved Pesto

This spinach pesto is the hidden soul of this dish and a cinch to make! Simply blend your crisp spinach, peppery basil leaves, complex and bold shredded Parmesan, earthy olive oil, roasted and salted nutty sunflower kernels, and a pinch of spicy crushed red pepper in a food processor or blender until they’re well incorporated and you’ve achieved a smooth consistency, then season to taste with salt and pepper. Set it aside until you’re ready to use it – reserving two tablespoons for your broken spaghetti – and faster than you can say “presto,” your pesto is done!

2. Chatea-OMG You’re Gonna Love This Dish

Once your mouthwatering Omaha Steaks Private Reserve® Chateaubriand Roast is fully thawed, remove it from the refrigerator and pat dry all over with paper towels to eliminate as much surface moisture as possible. Next, turn the roast so the short end is facing toward you, then use your sharp chef’s knife to carefully make a 1-inch incision along the long side. Continue to make 1-inch incisions along the seam on the inside of the cut, rolling the Chateaubriand out until it’s butterflied and 1-inch in thickness, then press it flat with your hands.

Now take half of your homemade spinach pesto (not including what’s reserved for the pasta) and coat a thin layer of it inside the butterflied Chateaubriand, leaving a 1-inch border without pesto. Carefully roll your Chateaubriand up from the long end without spilling any pesto, then tie off every 2 inches with the 8 pieces of butcher’s twine, spacing them evenly and double knotting them, then trim any excess twine for a clean look.

Next, rub your roast down with 2 tablespoons of olive oil and season it generously with salt and pepper before leaving it on the counter to come to room temperature over about 30 minutes. In the meantime, preheat your oven to 250 degrees Fahrenheit. Once your stuffed Chateaubriand has come to room temperature, place it on a roasting rack and put it on the center rack of your oven, cooking for about 45 minutes, or until the internal temperature reaches 115 degrees Fahrenheit for rare doneness. Prefer a different level of doneness? The Omaha Steaks Roast Cooking Chart is your go-to source for ensuring your gourmet food is cooked exactly how you want it!

Once your roast has reached 5 degrees below your desired doneness, add low-smoke-point grapeseed oil to an extra-large cast-iron pan and bring it to medium-high heat. Sear your cooked Chateaubriand for about 45 seconds on each side until they’re all beautifully browned, then add your creamy butter and use a spoon to butter-baste on each side for about 15 seconds. Now rest your Chateaubriand for 15 to 20 minutes to allow those mouthwatering juices to redistribute for the perfect bite.

3. Break Spaghetti – Not Dinner Plans

While your roast rests, we’re going to start cooking your broken spaghetti. If you’re a pasta purist who believes “breaking” spaghetti should be illegal, this next step may be new to you! And if you’re already a master spaghetti-breaker, don’t worry, we won’t tell anyone. For those amateurs, “broken spaghetti” is exactly what it sounds like! You simply bend dry spaghetti until it breaks into 1- to 1.5-inch pieces. Next, cook the spaghetti in boiling water until it has reached al dente doneness, strain, and then blanch by immediately plunging into cold water before straining again.

While your broken spaghetti cooks, add olive oil to a large saucepan and bring it to medium-high heat. Next, add your peppery red onions and sauté them for 30 seconds until they’re lightly brown and fragrant before adding sweet and acidic grape tomatoes and a pinch of salt, pepper, and hot crushed red pepper. Sauté it all until the tomatoes are slightly blistered (which should only take 90 seconds to 2 minutes) and then carefully press down and mash the tomatoes. Now it’s time to add your pungent garlic and lightly sauté it all for 15 seconds before adding savory chicken stock and reducing the liquid by half in volume over about 1 minute.

Pesto and spaghetti time! Add your reserved pesto and heavy cream and stir until it’s all well incorporated and beginning to boil, then reduce to medium heat and cook until the mixture is slightly thickened, which should only take about 1 minute. Next, add your al dente blanched spaghetti and peppery basil to the pan and toss it all together until the spaghetti is well coated, then add your nutty Parmesan and toss again until the sauce thickens and you achieve a cheese sauce-like consistency. Season to taste with salt and pepper and you’re done!        

4. Chatea-Oh Yea Time!

Almost time to plate! First, once your roast is rested, use the butcher’s twine as a guide and cut each slice so the twine is in the center. Add your olive oil to any remaining unused pesto to thin it out, then season it to taste with salt and pepper and get ready to plate! A meal this amazing deserves to be beautifully displayed. Start by placing your sauced broken spaghetti in the center of the plate, then top it with one spinach-pesto stuffed Chateaubriand slice, finish by drizzling it all with the thinned out spinach pesto, and then sit down to enjoy the delicious fruits of your labor!
