One of the great pleasures of my career is spending time each year working as a Culinary Educator aboard a cruise ship alongside my wife. She teaches baking & pastry while I focus on savory cooking and culinary techniques.

Our travels take us to fascinating ports around the world, providing opportunities to explore local markets and study regional cuisines.

I have a particular affection for the Mediterranean and always make it a point to seek out local variations of pesto, one of the world's great culinary treasures.

One evening aboard ship, the pasta station served rigatoni with a choice of pesto, marinara, or Alfredo sauce. The cook prepared each order by reheating the pasta in hot water and then finishing it briefly in a sauté pan with the selected sauce.

I watched in disbelief as he prepared to heat the pesto exactly the same way.

"Horror!" flashed through my mind.

Pesto is not a cooked sauce. Heating it aggressively dulls the fresh basil aroma, darkens its vibrant color, and diminishes the delicate flavors of basil, garlic, pine nuts, and extra virgin olive oil that make pesto so special.

I may have startled the cook when I quickly called out, "Please don't cook my pesto!"

Instead, I asked him to simply toss the hot rigatoni with the pesto off the heat, allowing the warmth of the pasta to gently release the fragrance and flavor of the basil.

The result was exactly as pesto was intended to be enjoyed—fresh, vibrant, aromatic, and unmistakably Mediterranean.

Rigatoni with Pesto & Asian Greens

Pesto is far more than the classic combination of basil, pine nuts, garlic, Parmesan cheese, and olive oil associated with the hills surrounding Genoa. At its heart, pesto is a technique rather than a recipe—a celebration of fresh greens, herbs, nuts, cheese, and good olive oil transformed into a vibrant sauce. Throughout the Mediterranean and increasingly in modern kitchens, cooks have embraced the flexibility of pesto by incorporating a wide range of ingredients dictated by season, geography, abundance and innovation.

I've posted several pesto recipes and received notes from my network about their favorite pestos with arugula, carrot tops, herbs, fennel, lamb's quarters, chickweed and even seaweed.

Each green brings its own personality to the mortar and pestle—or food processor—creating sauces that are unique expressions of season and place.

Pesto is more than simply delicious. Basil is rich in antioxidants and beneficial plant compounds. The aromatic essential oils found in basil have been studied for their anti-inflammatory and antimicrobial properties.

The choice of nuts can dramatically influence the character of a pesto. Although pine nuts are traditional, walnuts offer a more economical and sustainable alternative and give rich flavor and heart-healthy omega-3 fatty acids.

Be sure to always toast and skin the walnuts lightly before using them. Gentle toasting awakens their natural oils, deepens their flavor, and adds complexity and sweetness to the finished sauce.

Removing the thin papery skins from toasted walnuts eliminate bitterness. and olive oil.

Rigatoni with Pesto & Asian Greens

4 portions

Prep Time for Pesto: 30 min

Yield:  1 Cup


Ingredients                                          

2 Cups     Basil leaves, rinsed in cool water (I like Genovese & Lemon basil varieties)

1 Cup.      Lamb quarters, chickweed, arugula

2 Tbsp.   Fresh herbs (tarragon, chives, parsley)

3 Tbsp    Garlic, freshly peeled (rough chop)

4 Tbsp.   Walnuts, (toasted and peeled by rubbing in a clean towl)

6-8 oz     Extra Virgin Olive Oil

4 Tbsp    Parmesan Cheese, freshly grated (or to taste)

t.t.            Kosher Salt and Freshly Milled Black Pepper


4 Cups    Rigatoni, cooked

2 Cups.   Asian broccoli, choy, greens, cooked

2 Tbsp.   Calabrian hot pepper



How to Prepare Rigatoni with Pesto & Asian Greens

Step 1

Assemble all of the ingredients; I like to pick the smaller, tender basil leaves and always cut off any extra stem.


For the Walnuts: 

toast in the oven until golden brown, (about 8 minutes at 350 F) rub the warm walnuts in a kitchen towel to loosen much of the skin which results in a cleaner, sweeter, and more refined pesto. It is a small investment of time that pays enormous dividends in flavor.


If you are using a food processor, you can simply add all of the ingredients, pulse and wipe the sides with a rubber spatula-repeat until the ingredients are a smooth paste.



Begin by adding garlic to the mortar. Add a little salt and 1/3 of the basil; begin to slowly crush the basil with the pestle in a grinding method.


Add some of the walnuts and parmesan cheese and a little more basil and continue to grind. The basil may spill out a little so simple add it back into the mortar.


Continue adding walnuts, parmesan cheese, basil, greens and herbs, slowly drizzling in the EVOO as needed to help with the blending.

When all of ingredients have been ground to a beautiful, green, smooth paste, season to taste with salt and pepper.




Place cooked, hot rigatoni with a tablespoon of the warm pasta water into a bowl. Add the hot, cooked greens.


I recommend cooking the rigatoni and greens a few minutes before you plan to eat so you don't have to cool and reheat.

You can cook the rigatoni and greens, shock in cold water and then reheat if prefer.


Add 2 Tbsp of pesto per person to start and fold into the hot rigatoni and greens-add a little more if you like. 

Season to taste-I like adding grated cheese and spicy Calabrian chili oil or red pepper flakes.






It's best not to heat the pesto, just toss onto warm, freshly cooked macaroni and enjoy.

You can store pesto in the refrigerator or freezer in an air tight container with a little EVOO on the top to stop oxidation.

Chef Tom's Cooking Class Minute-Week 13 What the Heck Is Bone Broth? What’s your take on bone broth? Is it a new name for an old culinary tradition, or do you prepare yours differently? It's soup season! I use stock as the foundation for most of my soups. I’m clear on what a stock is, but what exactly is bone broth? I’m not totally sure where the culinary definition ends and the marketing begins. Broths seem to be healthy for us; they can provide protein, gelatin, collagen, electrolytes and amino acids, depending on the ingredients and how they’re prepared. The nutritional value varies, but they can help with hydration and protein intake. I’ve traveled throughout Asia & Europe to learn about stocks, broths and soups-I didn't find much information on bone broths. I even visited Chef Marco Canora, bone broth expert to discuss the recipes & techniques he uses to prepare his delicious Brodo bone broths at his restaurant Hearth in NYC. I think of bone broth as a traditional broth, similar to French petite marmite, Italian brodo, or the rich broths used as the foundation for Japanese ramen. One thing I know for sure: bone broth is not simply a collection of leftover meat and vegetable scraps you’ve saved in the freezer and boiled together when you feel like it! Chef Tom’s Tips: What’s the Difference? Stock: Traditionally prepared with bones, aromatics, seasonings & water. Broth: Prepared with meaty bones, aromatics, seasonings & water. Cooking time depends on the bones and the type of stock you’re making. Fish stock, or fumet, needs only about 30–40 minutes. Chicken stock generally simmers for 3–4 hours. White beef stock may take 5–6 hours. A few important points: I prefer to keep stock at a gentle simmer rather than a rolling boil. Some chefs bring the stock to a boil, strain and rinse the bones, and then start again with fresh water. I prefer not to use this method because I feel we may lose some flavor in the process. Carefully skim fat and impurities from the surface as the stock simmers. This helps produce a cleaner, clearer stock. Remember, stocks are recipes, too. Use consistent measurements so you can standardize your results and reproduce the same quality every time. Generally very little salt is added since stocks are used for a variety of cooking recipes. I also like to experiment with ingredients that add flavor and acidity, such as tomatoes and leeks. Mushrooms, ginger, lemongrass, saffron, star anise and Parmesan cheese rinds can all add another dimension to a broth. Each ingredient brings something different to the pot, so consider the flavor you want in the finished product.  Check out my new Soup e-cookbook, 'From the Pot to the Table' only $9.95!

Chef Tom’s Cooking Class Minute – 𝐖𝐞𝐞𝐤 12 𝐌𝐨𝐢𝐬𝐭-𝐇𝐞𝐚𝐭 𝐂𝐨𝐨𝐤𝐢𝐧𝐠: 𝐁𝐞𝐞𝐫 𝐚𝐧𝐝 𝐚 𝐆𝐨𝐨𝐝 𝐁𝐫𝐚𝐢𝐬𝐞 I like beer! And of course, beer is good for more than drinking! It adds a wonderful depth of flavor to soups, stews and braised meats. The trick is choosing the right beer for the dish. A light lager, a malty brown ale and a dark stout each bring something different to the dish. And no, you don't need to use your most expensive bottle to make a good stew! I was reminiscing about International Cuisine class at the Culinary Institute of America. Chef Bruno Ehlmer was my instructor. I still remember the delicious foods we made in class; goulash soup, coulibiac, paella and carbonnade à la flamande, the traditional Flemish beef & onion stew made with dark beer. These were my favorites. There are several local breweries in town, so I recently stopped by to pick up a Belgian-style brown beer for my beer-braised chicken stew with onions. I use local, seasonal ingredients whenever I can, & this seemed like a good excuse to visit a brewery and bring a little Belgian inspiration into my kitchen. I had a fantastic Octoberfest in my research that day… hahaha 𝐀 𝐅𝐞𝐰 𝐓𝐢𝐩𝐬 𝐟𝐨𝐫 𝐚 𝐩𝐫𝐨𝐩𝐞𝐫 𝐁𝐫𝐚𝐢𝐬𝐞 𝐋𝐨𝐰 𝐚𝐧𝐝 𝐬𝐥𝐨𝐰 cook it slowly in a flavorful, fairly thick gravy. In my experience, cooking at too high a temperature or in a thin liquid leaves the meat stringy instead of tender & succulent. 𝐁𝐮𝐢𝐥𝐝 𝐭𝐡𝐞 𝐟𝐥𝐚𝐯𝐨𝐫 𝐟𝐢𝐫𝐬𝐭 dredge the seasoned meat in sifted flour & brown it in clarified butter with sliced onions. This dish is flavored with mustard, vinegar, a little brown sugar & thickened with bread. 𝐋𝐞𝐭 𝐭𝐡𝐞 𝐨𝐯𝐞𝐧 𝐝𝐨 𝐭𝐡𝐞 𝐰𝐨𝐫𝐤 braise or stew in a covered pot in the oven. I like Le Creuset pots & pans. The heat is more even, and there is less chance of scorching the bottom of the pan. Uncover the pan for the final 30 minutes so the sauce can reduce and form a delicious glaze over the meat. 𝐂𝐡𝐨𝐨𝐬𝐞 𝐲𝐨𝐮𝐫 𝐜𝐡𝐢𝐜𝐤𝐞𝐧. I like Bell & Evans chicken thighs for this method. I often leave the skin on for flavor and brown it well before braising. I leave the bones in, but boneless thighs are perfectly fine. You can even cut them into bite-sized pieces for easier serving. The skin can be left on the plate or eaten, depending on your preference. Serve the stew with buttered noodles or boiled potatoes. Both are excellent for soaking up the gravy. One last tip: Don't assume that any beer will give you the same result. Think about how the bitterness, maltiness or roasted flavors will work with the meat & sauce. What beer do you like to cook with?

In my opinion, a great broth begins with a properly prepared stock. Homemade stock is one of the fundamentals I encourage every cook to learn. It is quite simple to prepare but takes some time, but much of that time is hands-off, and the results are worth the effort. I understand that there are plenty of stock 'products' on the market-bases, bouillon cubes, shelf stable boxes etc... these are simply not good. My approach is straightforward: start with good ingredients and give them the time they need. Fish stock requires only about 30–40 minutes, while chicken stock generally takes three to four hours. Beef stocks can take considerably longer, depending on the bones and the result you want. I prefer a gentle simmer rather than a rolling boil. It helps keep the stock clear, and careful skimming and proper straining make a difference in the finished product. There is plenty of room to experiment, too. Mushrooms, ginger, lemongrass, herbs, spices and Parmesan rinds can add their own character to a broth.
