I was once in the norwegian mountains and we had this primitive cooking without pots.
We actually only used sticks and hold them in fire. There are serveral primitive cooking methods on the web on youtube or in surivaland outdoor or priomitive skill books and alll the primitive skill gatheirngs in the USA.

What ever... why are dishes cooked in pans Paleo? Where did they had the iron in the paleo time?????
When do they discover to cook in pots? When they made the first clay pots??
Do you do any sort of primitive cooking at the fire???
Whether or not foragers do have pottery depends a lot on what one selects as one’s “ethnographic present.” Pottery was a fairly common part of the technological repertoire of foragers worldwide until Europeans introduced metal pots and pans, at which point many groups abandoned the use of clay containers. For example, if one relies on the descriptions of the San from the twentieth century, as most of us do, the ethnographies are virtually silent on the topic of pottery. But if one looks at the Later Stone Age archaeology of southern Africa, or the written accounts left by the first Dutch and English explorers to set foot in South Africa, it becomes evident that pottery was a fairly widespread component of Bushman culinary technology (Bollong et al. 1997; Mazel 1992; Rudner 1979). The earliest pottery thus far known appears in Late Pleistocene hunter–gatherer sites in eastern Russia, Japan, and China, with dates as early as ~13,000 radiocarbon years ago or up to 18,000 calibrated years ago (Boaretto et al. 2009; Keally et al. 2004; Kuzmin 2006; Zhang 2002). Ceramics also appear quite early in Africa, dating between 9,000 and 9,500 years ago in the central Sudan, as well as in northeast Niger and Libya (Garcea 2006; Haaland 1992). “In most of North Africa… the production of pottery and groundstone is independent of the origins of food domestication. It occurred about 3,000 years earlier, dating from around 9,000 years BP and 6,000 BP, respectively” (Garcea 2006:201).
Other containers, made out of gourds or skins, are not preserved in the archaeological record, but are regularly used by foragers.
Another ancestral' way to cook is to build a fire in a pit burn it down to coals layer leaves and food over the coals then bury it and leave for 4-8 hours - food cooked this way is beyond describing.
Regarding bone broth specifically, though none of your ancestors may have consumed it, it's an effective way to replace the calcium, magnesium, cartilage etc. that they were getting from other sources. Tastes good too.
Just because ancestors did or did not do something doesn't make it good or bad. Your ancestors also probably did a lot more murdering than you plan to, and ate with feces on their hands…
